Display device and method of manufacturing the same

1. A display device comprising:

a display panel comprising a substrate having a bent portion and a bending protective layer arranged on the bent portion of the substrate; and

an optical functional layer on the display panel and in contact with the bending protective layer, the optical functional layer having an accommodating portion configured to accommodate deformation of the optical functional layer.

2. The display device of claim 1 , further comprising a cover member arranged on the optical functional layer.

3. The display device of claim 2 , wherein the cover member comprises an opaque layer configured to block transmission of light.

4. The display device of claim 3 , wherein the accommodating portion overlaps the opaque layer in a plan view.

5. The display device of claim 2 , further comprising a first adhesive member arranged between the cover member and the optical functional layer.

6. The display device of claim 5 , wherein the first adhesive member shields the accommodating portion.

7. The display device of claim 5 , wherein the first adhesive member is configured to expose the accommodating portion to an outside.

8. The display device of claim 5 , wherein the accommodating portion is in the optical functional layer and the first adhesive member.

9. The display device of claim 1 , wherein the accommodating portion is a groove or hole arranged in the optical functional layer.

10. The display device of claim 9 , wherein at least a portion of an inner surface of the accommodating portion is inclined.

11. The display device of claim 9 , wherein at least a portion of an inner surface of the accommodating portion is curved.

12. The display device of claim 9 , wherein an inner surface of the accommodating portion is stepped.

13. The display device of claim 1 , further comprising at least one of a protective film, a panel protective member, a plate, a digitizer, or a cushion layer arranged on a surface of the display panel.

14. The display device of claim 1 , wherein the accommodating portion has a linear shape in a cross-sectional view.

15. A method of manufacturing a display device, the method comprising:

attaching a first upper cover film to a first surface of an optical functional layer;

attaching a lower cover film to a second surface of the optical functional layer;

removing a part of the first upper cover film;

removing a part of the optical functional layer; and

attaching a second upper cover film to the first surface of the optical functional layer.

16. The method of claim 15 , wherein the lower cover film comprises a first lower cover film and a second lower cover film, and

wherein the method further comprises removing the second lower cover film of the lower cover film.

17. The method of claim 16 , further comprising removing the first lower cover film and attaching the optical functional layer to a display panel.

18. The method of claim 17 , further comprising forming a bending protective layer in a bending area of the display panel to be in contact with an end of the optical functional layer.

19. The method of claim 16 , wherein the second lower cover film, the optical functional layer, and the second upper cover film are stacked together, and

wherein the method further comprises cutting the second lower cover film, the optical functional layer, and the second upper cover film to a certain length.

20. The method of claim 19 , further comprising arranging the optical functional layer from which the second lower cover film is removed, on a display panel.

21. The method of claim 20 , wherein an end of the second upper cover film is farther from an end of the display panel than an end of the optical functional layer is to the end of the display panel.

22. The method of claim 15 , wherein the part of the first upper cover film and the part of the optical functional layer are concurrently removed.

23. A method of manufacturing a display device, the method comprising:

arranging an optical functional layer on a display panel;

removing a part of the optical functional layer; and

forming a bending protective layer in a bending area of the display panel to be in contact with an end of the optical functional layer.

24. The method of claim 23 , further comprising removing a part of an upper cover film arranged on the optical functional layer.

25. The method of claim 24 , further comprising entirely removing the upper cover film on the optical functional layer.
