Abstract

A display device includes a window, a display module on a rear surface of the window, and including a folding area, and a non-folding area adjacent to the folding area, and a protective cover on a rear surface of the display module, and including a cover portion configured to cover the folding area and the non-folding area of the display module, and holding portions extending in a first direction, or in a second direction crossing the first direction, from the cover portion, and protruding outside the display module when viewed in a plane.

Claims (54)

1. A display device comprising:

a window;

a display module on a rear surface of the window, and comprising a folding area, and a non-folding area adjacent to the folding area; and

a protective cover on a rear surface of the display module, and comprising:

a cover portion configured to cover the folding area and the non-folding area of the display module; and

holding portions extending away from the display module in a first direction, and in a second direction crossing the first direction, from the cover portion, and protruding outside the display module when viewed in a plane, the first direction and the second direction being substantially parallel with the rear surface of the display module,

wherein each of the holding portions is provided in a shape of a flat plate that is parallel with the first and second directions.

2. The display device of claim 1 , wherein the window comprises a thin film glass.

3. The display device of claim 1 , wherein the non-folding area comprises a first non-folding area and a second non-folding area, which are separated by the folding area, and

wherein the cover portion comprises:

a first cover portion configured to support the folding area and the first non-folding area of the display module; and

a second cover portion configured to support the second non-folding area.

4. The display device of claim 3 , wherein the display module further comprises a non-bending area comprising the folding area and the non-folding area, and a bending area bent from the non-bending area, and

wherein the second cover portion covers the bending area.

5. The display device of claim 4 , wherein the second cover portion comprises:

a second body portion connected to the first cover portion, and configured to cover the second non-folding area; and

an arm portion extending in a direction crossing the second body portion, and configured to cover a portion of the bending area.

6. The display device of claim 5 , wherein the second cover portion further comprises a sidewall portion extending from the arm portion, and configured to cover a remaining portion of the bending area.

7. The display device of claim 5 , wherein the holding portions comprise a third holding portion extending from the arm portion in a direction away from the second body portion.

8. The display device of claim 3 , wherein the first cover portion comprises:

a first body portion connected to the second cover portion; a first portion extending from the first body portion in a direction away from the second cover portion; and a second portion extending from the first body portion in another direction crossing the direction.

9. The display device of claim 8 , wherein the first and second portions have a bar shape, and are perpendicular to each other when viewed in a plane.

10. The display device of claim 8 , wherein the second portion is configured to overlap the folding area.

11. The display device of claim 8 , wherein the holding portions comprise a first holding portion coupled to the first portion, and second holding portions coupled to the second portion.

12. The display device of claim 1 , wherein the holding portions are bent from the cover portion, and are configured to cover a portion of a side surface of the display module.

13. A display device comprising:

a folding area;

a first non-folding area adjacent to the folding area;

a second non-folding area adjacent to the folding area;

a window; a display module on a rear surface of the window, and comprising a non-bending area, and a bending area bent from the non-bending area; a first release film on the window;

a second release film under the display module; and

a protective cover under the second release film, and comprising:

a first cover portion configured to support the folding area and the first non-folding area of the display module;

a second cover portion extending from the first cover portion, and configured to support the second non-folding area and the bending area of the display module; and

holding portions respectively coupled to the first cover portion and the second cover portion.

14. The display device of claim 13 , further comprising adhesive members between the first and second release films, outside the display module, and configured to attach the first and second release films.

15. The display device of claim 13 , wherein the second release film comprises:

a first portion overlapping the first non-folding area;

a second portion overlapping the second non-folding area; and

a third portion overlapping the folding area, and wherein the protective cover further comprises an adhesive member attached to the third portion.

16. The display device of claim 15 , wherein a cutting line is defined between the first portion and the third portion, and between the second portion and the third portion.

17. The display device of claim 15 , wherein the first cover portion comprises:

a first portion on a lower surface of the first portion of the second release film, and extending in a first direction; and

a second portion on a lower surface of the third portion of the second release film, extending in a second direction crossing the first direction, and comprising the adhesive member.

18. The display device of claim 15 , wherein the second portion exposes a portion of the second non-folding area and the bending area.

19. The display device of claim 18 , wherein the second cover portion covers the bending area and the portion of the exposed non-folding area, and is spaced apart from the display module in a thickness direction.

20. A display device comprising:

a window;

a display module on a rear surface of the window, and comprising a folding area, and a non-folding area adjacent to the folding area; and

a protective cover on a rear surface of the display module, and comprising:

a cover portion covering the folding area and the non-folding area of the display module; and

holding portions extending away from the display module in a first direction, and in a second direction crossing the first direction, from the cover portion, protruding outside the display module when viewed in a plane, and connected to each other outside the display module,
