Fig. 2 is the display 10 and the second shading structure for indicating display device 1 involved in first embodiment of the invention The figure of part 20.Fig. 3 is by the partial enlargement of the image display area of display device 1 involved in first embodiment of the invention Figure.In addition, in Fig. 2, in order to illustrate display 10 and the second light obstructing member 20 are staggered record.

Image display area in the picture display face of display device 1 is configured with pixel PIX with rectangular.

The first opening portion (light emission goes out region) OP1 is provided in the region of each pixel PIX.As described above, this first Opening portion OP1 is formed in the first light obstructing member 13 (referring to Fig.1).First opening portion OP1 is for making from 3 (reference of backlight The opening portion that light Fig. 1) penetrates.It is the non-opening portion that the first opening portion OP1 is surrounded with clathrate around first opening portion OP1 That is, the first non-opening portion 19.Be opened and closed by MEMS shutter (not shown), thus to penetrated the light of first opening portion OP1 into Row shading or without shading.Display device 1 shows image in image display area as a result,.In the present embodiment, it first opens Oral area OP1 has rectangle.

The second opening portion (opening portion) OP2 of striated is formed in the second light obstructing member 20.By the second opening portion OP2's Extending direction is known as X-direction.Second opening portion OP2 extends across each pixel PIX in the X-axis direction.Second opening portion OP2 exists It is arranged in parallel in the Y direction orthogonal with X-direction.It is opening portion between the second opening portion OP2 in second light obstructing member 20 The second non-opening portion 21.In addition, the direction orthogonal with XY axial plane is known as Z-direction.

As shown in figure 3, the first opening portion OP1 of each pixel PIX and the second opening portion for being formed in the second light obstructing member 20 OP2 intersects.The longitudinal direction of first opening portion OP1 is Y direction, and the short side direction orthogonal with longitudinal direction is X-direction.

The portion covered by the second of the second light obstructing member 20 the non-opening portion 21 in the first opening portion OP1 of each pixel PIX Point by the second non-opening portion 21 come shading.By being projected from the cross section of the first opening portion OP1 and the second opening portion OP2 Light, so that the display of display device 1 floats such image.

First opening portion OP1 has two opening portions being arranged along the x axis that is, the first pair opening portion OP1a/ OP1b.In the present embodiment, first pair opening portion OP1a/OP1b is collectively referred to as the first opening portion OP1.

The width of X-direction in the width of first opening portion OP1 is set as W1X, the width of Y direction is set as W1Y. The width of X-direction in the width of second opening portion OP2 is set as W2X, the width of Y direction is set as W2Y.By pixel The period (pel spacing) of the Y direction of PIX is set as P_PIX。

In the present embodiment, in the Y-axis direction, W1Y > W2Y.In addition, in the X-axis direction, W1X < W2X.

Second opening portion OP2 continuous opening in the X-axis direction, therefore without generating, tool is rhythmic to rub in the X-axis direction That line.

What the position Chong Die with the second opening portion OP2 in the first opening portion OP1 was observed according to the observation in the Y-axis direction Position is different by each pixel PIX.

For example, center position observation image of the observer in the Y direction of the image display area of display device 1 is aobvious Show region.In this case, the picture for being configured at center in the visible pixel PIX arranged in the Y-axis direction of observer In plain PIX, the second opening portion OP2 is overlapped in the immediate vicinity of the first opening portion OP1.On the other hand, the observer is visible in Y In the pixel PIX of the position for being configured at end in pixel PIX arranged in axis direction, near the end of the first opening portion OP1 Overlap with the second opening portion OP2.

Therefore, moire fringes are generated sometimes according to the relationship of the first opening portion OP1 and the second opening portion OP2.

In the present embodiment, as an example, become W1Y:W1X=100:20 or so.First opening portion OP1 and Two opening portion OP2 orthogonally intersect.As an example, W2Y becomes 1/5 or so the length of W1Y.That is, becoming W1Y:W2Y= 100:20 or so.

As a result, in the region Chong Die with the second opening portion OP2 the first opening portion OP1, the value of W1X is smaller, therefore mole The ratio of the generation of line can be less.In addition, the value due to W2Y is smaller, so in the Y-axis direction, it can as unit of each pixel The positional shift (deviation of spatial frequency) of the first opening portion OP1 seen and the second opening portion OP2 is hidden by the second non-opening portion 21 Gear, therefore it is able to suppress the generation of moire fringes.

Also, the width (length of the Y direction of the second non-opening portion 21) of the second non-opening portion 21 is wider, therefore also can Enough generations for being bonded moire fringes caused by deviation inhibited due to display 10 with the second light obstructing member 20.

Wherein, in the case where using MEMS display as display 10, in order to swimmingly carry out MEMS shutter On-off action, the preferably longer rectangle in Y direction compared to X-direction.

In addition, display 10 is not limited to MEMS display, it is also able to use such as LCD (liquid crystal Display: liquid crystal display), PDP (plasma display panel) display, OLED (Organic light- Emitting diode: organic EL) the various displays such as display, LED (Light Emitting Diode) display.Make It, also can be by making the light emission of each pixel go out area in the case where with above-mentioned LCD, PDP display, OLED display, light-emitting diode display The aspect ratio in domain becomes 100:20, to inhibit the generation of moire fringes.

In addition, the light emission that the first opening portion OP1 is the pixel from display goes out region.Do not have backlight, In the case that self-emission device is disposed in the display of pixel, for the region of the pixel light emission.For example, being shown if OLED Device is then the region for being equipped with organic EL layer.

In the case where LCD, MEMS display, counter substrate 16 is fitted in device substrate 11.In addition, according to display 10 purposes is configured with the glass substrate and cover glass of touch sensor on device substrate 11.Moreover, each layer passes through OCA bonding.Therefore, the first light obstructing member 13 is more separate at a distance from the second light obstructing member 20.On the other hand, it is shown in OLED In the case where device, the first light obstructing member 13 can be relatively at a distance from the second light obstructing member 20.

In addition, continuously crossing over multiple first openings in the X-axis direction in the second opening portion OP2 as in the present embodiment In the case that portion OP1 extends, becomes W1Y:W1X=100:100, be also able to suppress the generation of moire fringes.

In addition, the configuration of the first opening portion OP1 and the second opening portion OP2 are respectively provided with spatial frequency, but since its is orthogonal, So the generation of invisible moire fringes.For the principle, it is illustrated using Figure 10.

Figure 10 is the figure for conceptually indicating the spatial frequency of the first opening portion OP1 and the second opening portion OP2.Figure 10's (a) it indicates the first opening portion OP1 and the second opening portion OP2 extended in X-direction and Y direction, is (b) to pass through arrow Amount indicates the figure of the spatial frequency of the first opening portion OP1 and the second opening portion OP2.

As shown in (a) of Figure 10, (b), even if the spatial frequency (week of the first opening portion OP1 and the second opening portion OP2B Phase) it is different, the generation of moire fringes is able to suppress if respective longitudinal direction is orthogonal.

In (b) of Figure 10, for f1 by the spatial frequency of the first opening portion of vector representation OP1, f2 passes through vector representation the The spatial frequency of two opening portion OP2.In this way, f1-f2 can be indicated as (b) of Figure 10.If the difference ratio f1 of vector f2 and f1 It is big then can not depending on thinking moire fringes, therefore be able to suppress moire fringes generation.This is because f1 is subtle to the journey that can not visually observe Degree.

In addition, the size of Fig. 2 and the second opening portion OP2 shown in Fig. 3 in addition in order not to cause moire fringes condition it Outside, it alsos for not damaging background parts in non-light and needs to consider non-aperture opening ratio.The size of second opening portion OP2 itself Inhibited depending on thinking excessive, therefore preferably.It will be aftermentioned for the size of second opening portion OP2.

(avoiding for moire fringes)

(other indexs for determining the size of the second opening portion OP)

Fig. 6 is the figure for indicating the relationship of the significance degree of width and the second opening portion OP of the second opening portion OP2.It is right using Fig. 6 Determine that other indexs of the size of the second opening portion OP2 are illustrated.First for preventing moire fringes from generating is opened using Fig. 5 Oral area OP1 and the relationship of the second opening portion OP2 are described.

For the size of the second opening portion OP2, other than consider that moire fringes generate prevents, it is also necessary to consider aperture opening ratio And second opening portion OP2 visuality.

Causing if the width big (aperture opening ratio of the second opening portion OP2 of even pixel PIX is big) of the second opening portion OP2 can The design showed in the second opening portion OP2 is had an X-rayed, texture (the beautiful degree of approach in kind) can not be shown.Another party The width in face, the second opening portion OP2 is smaller, is more able to maintain that the texture of the image from background portion (display 10), but corresponding The brightness on ground, the display image of display device 1 is dimmed.

In addition, even if the aperture opening ratio of the second opening portion OP2 of pixel PIX is small, if the width of the second opening portion OP2 is big, Cause visually to recognize the second opening portion OP2, it is difficult to as the material for having texture.

As shown in fig. 6, can not visually be observed in the case where the width of the second opening portion OP2 is 10 μm, 20 μm, 30 μm Second opening portion OP2.Therefore, it is known that if the second opening portion OP2 width be 30 μm hereinafter, if can be not reliably depending on recognizing second Opening portion OP2 and maintain display 10 show image texture, thus it is preferred that.

In addition, the second opening portion OP2 can be observed visually if the width of the second opening portion OP2 is 50 μm, 70 μm.Cause This, it is known that it is difficult to if 50 μm of short of width of the second opening portion OP2 depending on recognizing, and is able to maintain that the texture of image.

(effect)

Display device 1 has the first light obstructing member 13 and the second light obstructing member 20 in this way.First light obstructing member 13, which includes, to be shown The of the pixel PIX being arranged in mutually orthogonal X-direction and Y direction respectively in the image display area of device 10 One opening portion OP1 and the first non-opening portion 19 that the first opening portion OP1 is surrounded with clathrate.In the covering of second light obstructing member 20 It states image display area and configures, there is the second opening portion OP2 for arranging formation in the Y-axis direction and be set to the second opening portion The second non-opening portion 21 between OP2.

Moreover, the second non-opening portion 21 covers the first non-opening portion in the section for cutting off display device 1 along the y axis The face of side that is, the whole of surface 19a near point of observation 5 in 19.That is, becoming W1Y > W2Y.

Also, in the section for cutting off display device 1 along the y axis, from point of observation 5 towards the first plane A1 and second The side wall 21c of concern second opening portion OP2t of the straight line that plane A2 extends by the composition concern in the second opening portion OP2, The intersection point that is, point A22 of the side wall 21c of the side point of distance A21 in 21d and the second plane A2.If also, make the straight line with The point that first plane A1 intersects as point A12, make from point A22 is relative to the vertically extending vertical line of the first plane A1 and this is first flat It is Δ LY at a distance from point A13 that the point that face A1 intersects, which is point A13, point A22, then so that the mode that (formula 2) is set up sets W1Y, W2Y And Δ LY.

(W1Y-W2Y)/2 > Δ LY above-mentioned (formula 2)

Therefore, observer can be prevented when being shown in the image of image display area from point of observation 5 by the second opening Portion OP2 and see the first non-opening portion 19.Thereby, it is possible to prevent in the image generation mole for being shown in above-mentioned image display area Line.The generation for having rhythmic moire fringes in the Y-axis direction can especially be prevented.

In addition, the second opening portion OP2 is extended in a manner of intersecting across multiple first opening portion OP1 in the X-axis direction. Therefore, the generation for having rhythmic moire fringes in the X-axis direction can be prevented.

Alternatively, being also possible to the second opening portion OP2 is not to hand in the X-axis direction across multiple first opening portion OP1 Fork, but arrangement is formed in the X-axis direction.

In this case, the width of the X-direction of the first opening portion OP1 is set as W1X, by the X of the second opening portion OP2 The width of axis direction is set as W2X.In addition, becoming W1X > W2X.

Moreover, it can be, in the section for cutting off display device 1 along the x axis, from point of observation 5 towards the first plane The side wall of the separate side A21 in side wall of the straight line that A1 and the second plane A2 extends by constituting the second opening portion OP2t of concern With the intersection point that is, point A22 of the second plane A2, if using the point intersected with the first plane A1 as point A12, will from point A22 relative to The vertically extending vertical line of first plane A1 and the point of the first level-crossing are used as point A13, by point A12 conduct at a distance from point A13 Δ LX, then (formula 3) is set up.

(W1X-W2X)/2 > Δ LX above-mentioned (formula 3)

Thereby, it is possible to prevent observer when being shown in the image of image display area from point of observation 5 by the second opening Portion OP2 and see the first non-opening portion 19.Thereby, it is possible to prevent from generating in the image for being shown in above-mentioned image display area in X Have rhythmic moire fringes in axis direction.

In addition, compared with the case where making the first opening portion OP1 become W1Y:W1X=100:100, by making the first opening portion OP1 becomes W1Y:W1X=100:20, and the generation intensity of moire fringes can also be made to become Y direction: X-direction=100:20.

If being able to suppress the moire fringes of Y direction (100), even if remaining all X-directions (20) can not be inhibited Moire fringes in the case where, can also become inapparent degree.

Such as, it is believed that there is following situations, needs to become each design parameter in the tradeoff by brightness and non-aperture opening ratio Close to limiting value value in the case where, due to display 10 and the second light obstructing member 20 fitting when error, at a distance from viewpoint Variation, field angle variation, it has to allow not sufficiently eliminate has rhythmic moire fringes in the X-axis direction.

In this case, also by W1Y:W1X=100:20 is become, thus with the feelings as W1Y:W1X=100:100 Condition is compared, and the generation of moire fringes is able to suppress.

Herein, if becoming W1Y:W1X=100:20, compared with the case where becoming W1Y:W1X=100:100, opening portion The area divided becomes smaller, therefore worries that brightness reduces.But for example, using MEMS display the case where used backlight Recycling and reusing light using such method, prevent brightness from reducing such effort, so as to improve brightness reduction.
