Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to a first embodiment of the present application. The embodiment of the present application provides a display panel 1000, which includes a substrate 11, a substrate structure layer 12, a first organic layer 13, an active layer 14, a first insulating layer 15, a second organic layer 16, a first gate metal layer 17, a second insulating layer 18, a second gate metal layer 19, a third insulating layer 110, a third organic layer 120, a source-drain metal layer 130, a planarization layer 140, an anode 150, and a pixel defining layer 160.

The substrate structure layer 12 is disposed on the base plate 11. Specifically, the substrate structure layer 12 includes a barrier layer 121 disposed on the base plate 11 and a buffer layer 122 disposed on the barrier layer 121.

a first organic layer 13 is disposed on the substrate structure layer 12. The active layer 14 is disposed on the first organic layer 13. The first insulating layer 15 is disposed on the active layer 14. The second organic layer 16 is disposed on the first insulating layer 15. The first gate metal layer 17 is disposed on the second organic layer 16. A second insulating layer 18 is disposed on the first gate metal layer 17. A second gate metal layer 19 is disposed on the second insulating layer 18. The third insulating layer 110 is disposed on the second gate metal layer 19. The third organic layer 120 is disposed on the third insulating layer 110. The source-drain metal layer 130 is disposed on the third organic layer 120.

The planarization layer 140 is disposed on the source-drain metal layer 130. An anode 150 is disposed on the planarization layer 140. The pixel defining layer 160 is disposed on the anode 150.

The substrate structure layer 12, the first insulating layer 15, the second insulating layer 18, and the third insulating layer 110 are all inorganic layers. Alternatively, the material of the barrier layer 121 may be SiO 2. The material of the buffer layer 122 may be SiNx/SiO 2. The materials of the first, second, and third insulating layers 15, 18, and 110 may be SiO 2/SiNx.

The materials of the first organic layer 13, the second organic layer 16, and the third organic layer 110 may be organic photoresist materials.

the display panel 1000 further includes a first organism 101, a second organism 102, a third organism 103, a fourth organism 104, and a fifth organism 105. All organisms were used to relieve bending stresses.

The first body 101 is disposed on a side of the first gate metal layer 17 adjacent to the substrate 11 to relieve bending stress. The second body 102 is arranged on the side of the first gate metal layer 17 facing away from the substrate 11 and likewise serves to relieve the bending stress.

in the present first embodiment, the first organism 101 and the second organism 102 are respectively disposed on both end faces (first end face and second end face) of the first gate metal layer 17. Since the organic body has excellent flexibility, when the first gate metal layer 17 is bent, the first gate metal layer 17 generates a bending stress, and the bending stress is released by the first and second organic bodies 101 and 102, thereby protecting the first gate metal layer 17.

specifically, the first gate metal layer 17 includes a metal trace 171 and a first gate 172. The first gate electrode 172 is used to form a thin film transistor. The metal trace 171 includes a first surface and a second surface. The first surface and the second surface are oppositely arranged. The first surface is located on a side of the metal trace 171 close to the substrate 11, and the second surface is located on a side of the metal trace 171 far from the substrate 11.

The first organism 101 is arranged on one side of the first surface. The second organism 102 is disposed to one side of the second surface. With this arrangement, when the metal wire 171 is bent, the first and second organisms 101 and 102 serve to release the bending stress of the metal wire 171.

In the first embodiment, the first organic body 101 is in contact with the first surface of the metal trace 171, and the second organic body 102 is in contact with the second surface of the metal trace 171.

further, the metal trace 171 includes a first portion and a second portion. The width of the first portion is greater than the width of the second portion. A first organism 101 is disposed on the first portion. Since the larger the width of the metal trace 171 is, the more bending stress it receives, the more the bending stress needs to be released.

In the first embodiment, referring to fig. 2, based on the above structure, a first recess 121 is formed on the substrate structure layer 12. The first organic layer 13 is disposed on the substrate structure layer 12 and fills the first recess 121.

the metal trace 171 is correspondingly disposed on the second recess 151.

The third insulating layer 110 has a third recess 111. The third recess 111 penetrates through the second insulating layer 18 and exposes the metal trace 171. The third organic layer 120 is disposed on the third insulating layer 110 and fills the third recess 111.

the first organic layer 171 filling the first recess 121 and the second organic layer 16 filling the second recess 151 form the first organism 101. The third organic layer 120 filling the third recesses 111 is the second organism 102.

Alternatively, the shapes of the first recess 121, the second recess 151, and the third recess 111 may be hole-shaped or groove-shaped, respectively. The first recess 121, the second recess 151, and the third recess 111 may be formed by a photolithography process or a dry etching process.

When the first recess 121, the second recess 151 and the third recess 111 are in the hole-shaped structure, they are coaxially arranged on the vertical plane. On the horizontal plane, the first recesses 121 are spaced apart, the second recesses 151 are spaced apart, and the third recesses 111 are spaced apart.

Further, the third recess 111 is disposed along the extending direction of the metal trace 171. The distance between the third recesses 111 increases from the middle position to both side positions. So that the distance between the second organisms 102 increases from the middle position to the side positions. With such an arrangement, the bending stress releasing ability is improved.

in addition, a third organic body 103 is disposed on a side of the active layer 14 close to the substrate 11, and a fourth organic body 104 is disposed on a side of the active layer 14 opposite to the substrate 11. In the present first embodiment, the upper and lower faces of a part of the active layer 14 are provided with the third organic body 103 and the fourth organic body 104, respectively.

Specifically, the substrate structure layer 12 is opened with a fourth recess 122. The first organic layer 13 fills the fourth recess 122. Portions of the active layer 14 are correspondingly disposed on the fourth recess 122.

The first insulating layer 15 has a fifth recess 152. The fifth recess 152 is disposed corresponding to a portion of the active layer 14 and exposes the portion of the active layer 14. The second organic layer 16 fills the fifth recess 152.

the third insulating layer 110 has a sixth recess 112. The sixth recess 112 penetrates the second insulating layer 18 and exposes the second organic layer 16. The sixth recess 112 is disposed corresponding to the fifth recess 152. The third organic layer 120 fills the sixth recess 112.

The first organic layer 13 filling the fourth recess 122 is a third organism 103. The second organic layer 16 filling the fifth recess 152 and the third organic layer 120 filling the sixth recess 112 form the fourth organic body 104.

With this arrangement, when the active layer 14 is bent, the third and fourth organic bodies 103 and 104 serve to release the bending stress of the active layer 14.

Optionally, the fourth recess 122, the fifth recess 152 and the sixth recess 112 are hole-shaped or groove-shaped.

When the fourth recess 122, the fifth recess 152 and the sixth recess 112 are hole-shaped structures, they are coaxially arranged on a vertical plane. On the horizontal plane, the fourth recesses 122 are spaced apart, the fifth recesses 152 are spaced apart, and the sixth recesses 112 are spaced apart.

further, the fourth recess 122 is disposed along the extending direction of the active layer 14. The distance between the fourth recesses 122 increases from the middle position to both side positions. So that the distance between the third organisms 103 increases from the middle position to the both side positions. With such an arrangement, the bending stress releasing ability is improved.

In addition, in the present first embodiment, the fifth organisms 105 are disposed on one or both sides of the active layer 14 and/or the metal traces 171.

specifically, the fifth organic body 105 is disposed between the active layer 14 and the metal trace 171. Recesses are formed at the positions of the fifth organisms 105 so that at least one of the first organic layer 13, the second organic layer 16 and the third organic layer 120 fills the recesses to form the fifth organisms 105.

After the depression is dug, the organic layer is filled in the depression to form the fifth organism 105. With the arrangement, the area of the dug and sunken part of the display panel is increased, more fifth organisms 105 are filled, the bending stress of the inorganic layers on two sides of the fifth organisms 105 can be released, and the bending resistance of the display panel is improved.

it should be noted that fig. 1 of the first embodiment only shows the display area of the display panel 1000, but the scope of the present application is not limited thereto. Such as the metal wiring 171, may also be drawn out to the non-display area, and thus the organic body may be disposed in the non-display area.
