Abstract

A structure for a display device and a display device are provided. A structure for a display device includes a surface of which at least a portion thereof is not flat, and another surface that is flat. A display device includes: a display panel; and a structure contacting the display panel, and at least some of a first surface of the display panel may have a first curved shape, the structure may have a second surface contacting the first surface of the display panel, at least a portion of the second surface of the structure may have a second curved shape, and the structure may include a third surface that is opposite the second surface and is flat, and a driver is attached and fixed to the flat third surface of the structure.

First claim

What is claimed is:

1. A structure for a display device including a display panel having a convex shape in a first direction, comprising:
a first layer including a first surface and a second surface opposite the first surface, wherein the first surface has a convex shape in the first direction and the second surface is flat;
a second layer disposed on the second surface of the first layer according to a second direction opposite to the first direction and being flat; and
a third layer disposed on the second layer and being flat.

2. The structure for a display device of claim 1 , wherein the first layer and the third layer have adherence.

3. The structure for a display device of claim 2 , wherein at least a portion of the first surface of the first layer has a plurality of convex portions and a plurality of concave portions.

4. The structure for a display device of claim 3 , wherein convex portions of the plurality of convex portions have a polygonal flat shape.

5. The structure for a display device of claim 4 , wherein the convex portions have a triangular, quadrangular, or hexagonal flat shape.

6. The structure for a display device of claim 2 , wherein an edge of at least one of the second layer and the third layer protrudes more than an edge of the first layer.

7. The structure for a display device of claim 1 , wherein at least a portion of the first surface of the first layer has a plurality of convex portions and a plurality of concave portions.

8. The structure for a display device of claim 1 , wherein an edge of at least one of the second layer and the third layer protrudes more than an edge of the first layer.

9. The structure for a display device of claim 8 , wherein at least a portion of the first surface of the first layer has a plurality of convex portions and a plurality of concave portions.

10. The structure for a display device of claim 9 , wherein convex portions of the plurality of convex portions have a polygonal flat shape.

11. The structure for a display device of claim 10 , wherein the convex portions have a triangular, quadrangular, or hexagonal flat shape.

12. A display device comprising:
a display panel; and
a structure disposed on the display panel,
wherein a first surface of the display panel has a concave shape in a first direction,
the structure includes a second surface adjacent to the first surface of the display panel and the second surface has a convex shape corresponding to the concave shape of the first surface of the display panel in the first direction, and
the structure includes a third surface opposite the second surface, wherein the third surface is flat.

13. The display device of claim 12 , wherein the concave shape of the display panel and the convex shape of the structure are combinable and opposite to each other.

14. The display device of claim 12 , further comprising a driver connected to the display panel, wherein the driver contacts and is fixed to the third surface of the structure.

15. The display device of claim 14 , wherein the structure includes a first layer including the second surface, a second layer disposed on the first layer, and a third layer disposed on the second layer and including the third surface, and
the first layer and the third layer have adherence.

16. The display device of claim 15 , wherein at least a portion of the second surface of the first layer has a plurality of convex portions and a plurality of concave portions.

17. The display device of claim 16 , wherein convex portions of the plurality of convex portions have a polygonal flat shape.

18. The display device of claim 17 , wherein the convex portions have a triangular, quadrangular, or hexagonal flat shape.

19. The display device of claim 14 , wherein
the structure includes a first layer including the second surface, a second layer disposed on the first layer, and a third layer disposed on the second layer and including the third surface, and
an edge of at least one of the second layer and the third layer protrudes more than an edge of the first layer.

20. A display device comprising:
a display portion comprising a display panel including a first surface and a structure attached to the display panel and including a second surface opposite the first surface, wherein the first surface has a convex shape, and the second surface is flat; and
a driver connected to the display portion and adhered and fixed to the second surface.

21. The display device of claim 20 , wherein
the structure includes a first layer disposed on the display panel, a second layer disposed on the first layer, and a third layer disposed on the second layer and including the second surface, and
an edge of at least one of the second layer and the third layer protrudes more than an edge of the first layer to cover an edge of the display panel.

22. The display device of claim 21 , wherein at least a portion of a surface of the first layer has a plurality of convex portions and a plurality of concave portions.

23. The display device of claim 22 , wherein convex portions of the plurality of convex portions have a polygonal flat shape.

24. The display device of claim 23 , wherein the convex portions have a triangular, quadrangular, or hexagonal flat shape.
