Abstract

A display apparatus includes a bending area and a non-bending area, a display panel including a first panel area, a second panel area, and a panel bending portion that is bent such that at least a portion of the first panel area overlaps a portion of the second panel area, the display panel may have a curvature in the bending area, and a spacer between the first panel area and the second panel area, the spacer including a first portion in the bending area and a second portion in the non-bending area, wherein the first portion of the spacer is different in material from the second portion, and wherein the first portion of the spacer may have a curvature in the bending area substantially equal to a curvature of the display panel in the bending area.

Claims (31)

1. A display apparatus comprising:

a bending area and a non-bending area;

a display panel comprising a first panel area, a second panel area, and a panel bending portion that is bent such that at least a portion of the first panel area overlaps a portion of the second panel area, the display panel being to have a curvature in the bending area; and

a spacer between the first panel area and the second panel area, the spacer comprising a first portion in the bending area and a second portion in the non-bending area,

wherein the first portion of the spacer is different in material from the second portion, and

wherein the first portion of the spacer is to have a curvature in the bending area substantially equal to a curvature of the display panel in the bending area.

2. The display apparatus of claim 1 , wherein the first portion is less in hardness than the second portion.

3. The display apparatus of claim 2 , wherein the first portion comprises a porous material.

4. The display apparatus of claim 3 , wherein the first portion has greater adhesive force than the second portion.

5. The display apparatus of claim 4 , wherein the porous material comprises a pore filled with an adhesive.

6. The display apparatus of claim 1 , further comprising an integrated circuit (IC) chip on the second panel area of the display panel.

7. The display apparatus of claim 6 , wherein the spacer further comprises a third portion located in the non-bending area and overlapping the IC chip, and

wherein the third portion is different in material from the second portion.

8. The display apparatus of claim 7 , wherein the third portion is less in hardness than the second portion.

9. The display apparatus of claim 8 , wherein the first portion is less in hardness than the second portion.

10. The display apparatus of claim 9 , wherein the first portion and the third portion are the same in material.

11. The display apparatus of claim 10 , wherein the first portion and the third portion each comprise a porous material.

12. The display apparatus of claim 9 , wherein the first portion and the third portion are at the same layer.

13. The display apparatus of claim 1 , further comprising a panel protective layer on a lower surface of the display panel, the panel protective layer being to have a curvature in the bending area substantially equal to the curvature of the display panel in the bending area.

14. The display apparatus of claim 13 , wherein the panel protective layer comprises at least one of a light absorption layer to absorb light incident on the light absorption layer from the outside, a cushion layer to absorb an impact from the outside, or a heat dissipation layer to dissipate heat of the display panel.

15. The display apparatus of claim 1 , further comprising a cover window on an upper surface of the display panel, the cover window being to have a curvature in the bending area substantially equal to a curvature of the display panel in the bending area.

16. A display apparatus comprising:

a bending area and a non-bending area;

a display panel comprising a first panel area, a second panel area, and a panel bending portion, the panel bending portion being between the first panel area and the second panel area and having a third panel area that is bent, wherein the display panel is to have a curvature in the bending area; and

a spacer between the first panel area and the second panel area, the spacer being to have a curvature in the bending area substantially equal to the curvature of the display panel in the bending area, and having at least one patterned portion, the at least one patterned portion of the spacer being different in material from an adjacent portion of the spacer adjacent to the at least one patterned portion.

17. The display apparatus of claim 16 , further comprising an integrated circuit (IC) chip on the second panel area of the display panel,

wherein the at least one patterned portion of the spacer comprises at least one of a first portion located in the bending area, a second portion located in the non-bending area or a third portion located in the non-bending area and overlapping the IC chip.

18. The display apparatus of claim 17 , wherein the first portion is less in hardness than the adjacent portion of the spacer adjacent to the first portion, and

the third portion is less in hardness of the adjacent portion of the spacer adjacent to the third portion.

19. The display apparatus of claim 18 , wherein the first portion and the third portion each comprise a porous material.

20. The display apparatus of claim 18 , wherein the first portion and the third portion are at the same layer.
