Abstract

Embodiments of the present disclosure provide a display substrate, a method of manufacturing a display substrate, and a display apparatus. The display substrate includes a display area and a non-display area. The display substrate further includes: a base substrate; and a first insulating layer and a second insulating layer disposed on the base substrate in sequence. The first insulating layer includes a first slot located in the non-display area and filled with a first filler, and the second insulating layer includes a second slot located in the non-display area.

Claims (37)

1. A display substrate comprising: a display area and a non-display area, wherein the display substrate further comprises: a base substrate; and a first insulating layer and a second insulating layer disposed on the base substrate in sequence, wherein:

the first insulating layer comprises at least two first slots located in the non-display area and filled with a first filler,

the second insulating layer comprises at least two second slots located in the non-display area,

there is no overlap between orthogonal projections of the first slots on the base substrate and orthogonal projections of the second slots on the base substrate,

between orthogonal projections of any two adjacent first slots on the base substrate, there is an orthogonal projection of one second slot on the base substrate, and

between orthogonal projections of any two adjacent second slots on the base substrate, there is an orthogonal projection of one first slot on the base substrate.

2. The display substrate of claim 1 , wherein the second slots are filled with a second filler.

3. The display substrate of claim 1 , wherein the first slots comprise first through holes passing through the first insulating layer, and the second slots comprise second through holes passing through the second insulating layer.

4. The display substrate of claim 2 , wherein the first filler and the second filler are the same.

5. The display substrate of claim 2 , wherein:

the first filler comprises polyvinylidene fluoride, polyurethane or polytetrafluoroethylene, and

the second filler comprises polyvinylidene fluoride, polyurethane or polytetrafluoroethylene.

6. The display substrate of claim 1 , wherein:

the first insulating layer comprises: a barrier layer; and a buffer layer located on a side of the barrier layer facing away from the base substrate, and

the second insulating layer comprises: a gate insulating layer; and an interlayer insulating layer located on a side of the gate insulating layer facing away from the base substrate.

7. A display apparatus comprising the display substrate of claim 1 .

8. A method of manufacturing a display substrate, wherein the display substrate comprises a display area and a non-display area, and the method comprises:

providing a base substrate;

forming a first insulating layer and a second insulating layer on the base substrate in sequence, wherein the first insulating layer comprises at least two first slots located in the non-display area, and the second insulating layer comprises at least two second slots located in the non-display area; and

filling the first slots with a first filler;

wherein there is no overlap between orthogonal projections of the first slots on the base substrate and orthogonal projections of the second slots on the base substrate; and

wherein:

between orthogonal projections of any two adjacent first slots on the base substrate, there is an orthogonal projection of one second slot on the base substrate, and

between orthogonal projections of any two adjacent second slots on the base substrate, there is an orthogonal projection of one first slot on the base substrate.

9. The method of claim 8 , wherein forming the first insulating layer and the second insulating layer on the base substrate in sequence comprises:

forming the first insulating layer on the base substrate;

forming the first slots, located in the non-display area, in the first insulating layer;

forming a second insulating layer on the first insulating layer; and

forming the second slots, located in the non-display area, in the second insulating layer, and

the method further comprises: filling the second slots with a second filler.

10. The display substrate of claim 1 , wherein each of the first slots and the second slots partially surrounds the display area.

11. The display substrate of claim 1 , wherein at least one of the first slots and the second slots has a “Π” shape.

12. The display substrate of claim 1 , wherein the first filler comprises a flexible hydrophobic material.

13. The display substrate of claim 2 , wherein at least one of the first filler or the second filler comprises a flexible hydrophobic material.

14. The method of claim 8 , wherein:

the first insulating layer comprises: a barrier layer; and a buffer layer located on a side of the barrier layer facing away from the base substrate, and

the second insulating layer comprises: a gate insulating layer; and an interlayer insulating layer located on a side of the gate insulating layer facing away from the base substrate.
