The sub-pixel unit comprises a TFT side substrate, a CF side substrate and liquid crystal clamped between the TFT side substrate and the CF side substrate, and the ultraviolet vertical alignment mode is as follows: the lateral distance (spacing between adjacent data lines) of the sub-pixel unit is used as the period of the TFT side UV2A mask repeating unit²The light-shielding bar of the A photomask covers the left half part of the sub-pixel (the direction marked by A in FIG. 1), and the light leakage gap covers the right half part of the sub-pixel unit (the direction marked by B in FIG. 1); taking the longitudinal direction distance of the sub-pixel unit as the CF side UV²Period of A photomask, CF side UV²The light-shielding bars of the A mask cover the upper half of the sub-pixels (direction marked by C in FIG. 1), and the CF side UV²The light leakage slit of the a mask covers the bottom half of the pixel (direction marked by D in fig. 1). The directions of the four dashed arrows in fig. 1 are the rotation directions of the liquid crystal molecules in the sub-pixel unit.

FIG. 2 is a schematic diagram of a structure of applying a force to liquid crystal molecules by a fringe electric field of a pixel electrode in a sub-pixel unit, using UV²The liquid crystal display panel in the a-alignment mode has dark fringes as shown in fig. 3 in a white state due to dual effects of UV photo-alignment at both sides of the TFT and the CF and an electric field at edges of the pixel electrodes, and the dark fringes can reduce transmittance of the display and affect a display effect of the liquid crystal display panel.

Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of embodiments of the disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

Albeit UV²The A technique has been said to be perfect as the most advanced VA technique, UV²The transmittance of the A technology on a low-resolution liquid crystal display panel is higher than that of other VA technologies. However, the inventors found that when the resolution of the liquid crystal display panel is improved, UV is applied²The transmittance of the A technology is reduced compared with that of the PSMVA (Polymer-stabilized Multi-Domain vertical Aligned) panel which is mainstream at present.

The present exemplary embodiment first provides a liquid crystal display panel. Referring to fig. 4, the liquid crystal display panel may include an array substrate 1, a color filter substrate 2, a pixel electrode 3 and a liquid crystal layer 4, wherein the pixel electrode 3 is located on a surface of the array substrate 1, the liquid crystal layer 3 is sandwiched between the array substrate 1 and the color filter substrate 2, a light rotation agent is doped in the liquid crystal layer 4, and a twist amount of liquid crystal molecules in the liquid crystal layer satisfies the following condition: 0.05 ≦ d/p ≦ 0.25, where d represents the thickness of the liquid crystal layer and p represents the pitch of the liquid crystal molecules.

By doping the optical rotation agent into the liquid crystal molecules of the liquid crystal display panel, the phase difference is generated at the position of the original dark fringe due to the action of the optical rotation agent, and the penetration rate at the dark fringe position of the liquid crystal display panel is improved.

Next, each part of the above-described liquid crystal display panel in the present exemplary embodiment will be described in more detail with reference to fig. 4 to 13.

In one embodiment, the array substrate 1 includes a plurality of criss-cross scan lines and data lines, and the pixel electrodes 3 are defined by the intersections of the scan lines and the data lines. The pixel electrode 3 may be an ITO (indium tin oxide) electrode, but is not limited thereto. The liquid crystal display panel of this embodiment may further include an alignment layer, and the liquid crystal molecules in the liquid crystal layer 4 are controlled to tilt along the ultraviolet direction in the Ultraviolet (UV) vertical alignment mode by using the polymer material of the alignment layer. In this embodiment, the optical rotation agent may be a mixture of a plurality of chiral agents, but is not limited thereto. After the optical rotation agent is added into the liquid crystal layer 4, the liquid crystal molecules in the liquid crystal layer are twisted along an axial direction to form a helical structure, the pitch of the liquid crystal molecules forming the helical structure is p, the thickness of the liquid crystal layer is d, d/p represents the twisting amount of the liquid crystal molecules, and the pitch p of the liquid crystal molecules can be determined by adjusting the addition amount of the optical rotation agent. Referring to fig. 5, fig. 5 shows a graph of the relationship between d/p and transmittance at different driving voltages of a liquid crystal display panel at a resolution of 160ppi, wherein the horizontal axis represents the driving voltage and the vertical axis represents the transmittance, and 6 curves in the graph represent the transmittance of the liquid crystal display panel at d/p of 0, 0.1, 0.15, 0.2, 0.25 and 0.3, respectively. As shown in FIG. 5, when d/p is smaller, the transmittance of the liquid crystal display panel is lower, and as d/p increases, the transmittance of the liquid crystal display panel also increases, but when d/p is greater than 0.25, the transmittance of the liquid crystal display panel decreases, so that the range of d/p can be selected to be 0.05. ltoreq. d/p.ltoreq.0.25.

In one embodiment, the resolution of the liquid crystal display panel may be 80ppi or more, UV²The transmittance of the a technology decreases rapidly at high resolution, so that the resolution of the liquid crystal display panel in this embodiment may be at least 80 ppi. Through experiments, the embodiment of the disclosure is more suitable for a liquid crystal display panel with high resolution, and under the condition of high resolution, the transmittance of the liquid crystal display panel can be better improved by matching with the design of the rhombus slit structure of the optical rotation agent and the pixel electrode.

In an embodiment, referring to fig. 6, fig. 6 shows a schematic diagram of a pixel electrode of a liquid crystal display panel, on the basis of the above embodiment, the pixel electrode 3 may further include an electrode substrate, the electrode substrate includes a first region 5, a second region 6, a third region 7 and a fourth region 8, the first region, the second region, the third region and the fourth region are formed by dividing a horizontal line 9 and a vertical line 10 and are sequentially distributed along a clockwise direction; wherein the first, second, third and fourth regions each comprise a plurality of parallel slits 11, all slits of the four regions being overall rhomboid-shaped. The horizontal line 9 may be a horizontal center line and the vertical line 10 may be a vertical center line, but is not limited thereto. For convenience of production, the widths of the slits 11 in the four regions may be the same, and the intervals of the slits 11 may also be the same, which is not limited in this embodiment. Unlike the conventional pixel electrode in the shape of a Chinese character 'mi' or a 'skeleton', reference may be made to the prior art, which is not repeated herein, and in this embodiment, the latticed slits and the UV of the pixel electrode 3 are not repeated²In the technology A, the alignment directions of liquid crystal molecules are consistent, the inversion of the liquid crystal when voltage is applied can be better normalized, the generation of dark stripes is reduced, and the penetration rate of the liquid crystal display panel is improved. Referring to FIG. 7, FIG. 7 is a graph showing the relationship between d/p and transmittance at a resolution of 160ppi for a liquid crystal display panel including diamond-shaped slit pixel electrodes, where the horizontal axis represents the driving voltage and the vertical axis represents the transmittance, and 6 curves in the graph represent d/p min0, 0.1, 0.15, 0.2, 0.25, 0.3, respectively. Comparing fig. 5 and fig. 6, it is found that the transmittance of the liquid crystal display panel can be improved better when the rhombus-shaped slits in the present embodiment are combined with the optical rotation agent.

In one embodiment, the slits 11 in the first region 5 are at an angle θ to the horizontal 9₁The angle between the slits 11 in the second region 6 and the horizontal 9 is theta₂The angle between the slit 11 and the horizontal line 9 in the third region 7 is θ₃The angle between the slit 11 and the horizontal line 9 in the fourth region 8 is θ₄Wherein theta is more than or equal to 35 degrees₁≤55°，125°≤θ₂≤145°，215°≤θ₃≤235°，305°≤θ₄Is less than or equal to 325 degrees. For example, in one specific example, θ₁Is 45 DEG theta₂Is 135 deg., theta₃Is 225 DEG theta₄315 °, the slits 11 under the angle are more matched with the alignment direction of the liquid crystal molecules, and further, the penetration rate of the liquid crystal display panel can be better improved under the condition that the latticed slit structure under the angle is matched with the optical rotation agent.

In one embodiment, the slits 11 between at least two adjacent ones of the first 5, second 6, third 7 and fourth 8 regions are spaced apart by a first predetermined distance 12, the first predetermined distance 12 being within 10 μm. The preset distance is set between the slits 11 of at least two adjacent regions to keep the circuit of the pixel electrode conducting, and the width of the first preset distance 12 is not too wide, which may affect the transmittance of the liquid crystal display panel. For example, in a specific embodiment, referring to fig. 8, fig. 8 shows a schematic diagram of a pixel electrode of the liquid crystal display panel, the pixel electrode has a first predetermined distance 12 in the horizontal direction, that is, the first region 5 is connected to the slits 11 of the second region 6, the third region 7 is connected to the slits 11 of the fourth region 8, the first predetermined distance 12 is between the slits 11 of the first region 5 and the fourth region 8, and the first predetermined distance 12 is between the slits 11 of the second region 6 and the third region 7. For another example, referring to fig. 9, fig. 9 shows a schematic diagram of a pixel electrode of the liquid crystal display panel, the pixel electrode has a first predetermined distance 12 in the vertical direction, that is, the first region 5 is connected to the slit 11 of the fourth region 8, the second region 6 is connected to the slit 11 of the third region 7, the first predetermined distance 12 is between the first region 5 and the slit 11 of the second region 6, and the first predetermined distance 12 is between the third region 7 and the slit 11 of the fourth region 8.

Alternatively, in some embodiments, the slits 11 between at least two adjacent regions of the four regions may be arranged in a staggered manner. In a specific embodiment, referring to fig. 10 and 11, fig. 10 shows a schematic diagram of one pixel electrode of the liquid crystal display panel, fig. 11 is a partial enlarged view of fig. 10, the widths of the slits 11 in the first region 5, the second region 6, the third region 7 and the fourth region 8 are the same, the pitch of the slits 11 is also the same, the first region 5 and the second region 6, the third region 7 and the fourth region 8 are arranged in a staggered manner in the horizontal direction, and the first region 5 and the fourth region 8, the second region 6 and the third region 7 are arranged in a staggered manner in the vertical direction.

In one embodiment, referring to fig. 12, fig. 12 shows a schematic diagram of one pixel electrode of the liquid crystal display panel, the left edge of the first region 5 is provided with the first electrode region 13; the upper side edge of the second region 6 is provided with a second electrode region 14; a third electrode region 15 is arranged at the right edge of the third region 7; the lower side edge of the fourth region 8 is provided with a fourth electrode region 16. Because of the dual action of the UV optical alignment at the two sides of the array base 1 and the color film substrate 2 and the fringe electric field of the pixel electrode, the liquid crystal at the left side edge of the first region 5, the upper side edge of the second region 6, the right side edge of the third region 7 and the lower side edge of the fourth region 8 collide with each other to generate dark fringes, the first electrode region 13, the second electrode region 14, the third electrode region 15 and the fourth electrode region 16 are respectively arranged near the fringe dark fringes of the pixel electrode, the electrode acting force can resist the acting force at the edge of the pixel electrode, the fringe acting force of the pixel electrode is eliminated to a certain extent, and then the fringe dark fringes of the pixel electrode is eliminated to a certain extent.

In one embodiment, the first electrode regions 13, the second electrode regions 14, the third electrode regions 15, and the fourth electrode regions 16 each have a width d₁(ii) a The first region 5, the second region 6, the third region 7 and the fourth region 8 are allSpaced from the peripheral edge of the electrode base body by a second preset distance d₂Wherein d is₂<d₁And d is₁+d₂Less than or equal to 10 mu m. In one embodiment, the second predetermined distance d₂May be equal to zero. Second predetermined distance d₂It is not suitable for the width to be too wide, which affects the width of the slits 11 in the four regions, and it is not suitable for the width to be too narrow, otherwise, the acting force of the four electrode regions is difficult to eliminate the edge acting force of the pixel electrode, so that the effect of eliminating the dark fringe at the edge of the pixel electrode is not obvious.

In particular, the first slit region 17, the second slit region 18, the third slit region 19 and the fourth slit region 20 may each include a plurality of parallel slits 11. The four slit areas are respectively arranged near the edge dark stripes of the pixel electrode, so that liquid crystal molecules at the edge dark stripes of the pixel electrode can be better aligned, and the edge dark stripes of the pixel electrode are eliminated to a certain extent.

In one embodiment the slits 11 in the first slit area 17 are at an angle r to the horizontal line 8₁The slits 11 in the second slit area 18 enclose an angle r with the horizontal line 8₂The slits 11 in the third slit area 19 enclose an angle r with the horizontal line 8₃The angle of the slits 11 in the fourth slit area 20 with the horizontal line 8 is r₄Wherein r is more than or equal to 35 degrees₁≤55°，125°≤r₂≤145°，215°≤r₃≤235°，305°≤r₄Is less than or equal to 325 degrees. For example, in one specific example, r₁Is 45 DEG, r₂Is 135 DEG, r₃Is 225 DEG, r₄The angle is 315 °, the slit 11 at the angle is more matched with the alignment direction of the liquid crystal molecules, and further, the slit area at the angle can better eliminate the edge dark fringe of the pixel electrode.

In one embodiment, the first slit region 17, the second slit region 18, the third slit region 19 and the fourth slit region 20 are all spaced a third predetermined distance d from the edge of the electrode base body₃Wherein, in order to keep the circuit of the pixel electrode connected, 0<d₃<10 mu m; the first slit region 17, the second slit region 18, the third slit region 19 and the fourth slit region 20 all have a width d₄Wherein, 0<d₄Less than or equal to 10 mu m, the width d of the four slit areas₄It is not desirable to narrow, otherwise, the alignment effect of the four slit regions on the liquid crystal molecules is not obvious, so that the effect of eliminating the dark fringes at the edges of the pixel electrode is not obvious.
