Abstract

A display device includes a window, a display module on a rear surface of the window and including a non-bending area and a bending area configured to bend at a periphery of the non-bending area, a protective cover on a rear surface of the display module to protect the bending area of the display module, and a stopper coupled with the protective cover to limit a movement of the window.

Claims

1. A display device comprising:

a window;

a display module on a rear surface of the window and including a first area and a second area configured to bend at a periphery of the second area;

a protective cover on a rear surface of the display module to protect the bending area of the display module; and

a stopper coupled with the protective cover to limit a movement of the window.

2. The display device of claim 1, wherein the stopper comprises a protruding portion protruding from the protective cover.

3. The display device of claim 2, wherein the protruding portion comprises:

a first protruding portion protruding from the protective cover in a first direction parallel to a first periphery of the window; and

a second protruding portion obliquely extending from the first protruding portion in a second direction different from the first direction.

4. The display device of claim 3, wherein the window comprises a strength reinforcing portion provided on a corner of the window adjacent the first periphery.

5. The display device of claim 4, wherein the second protruding portion overlaps the strength reinforcing portion and is engaged with the strength reinforcing portion to limit a movement of the window.

6. The display device of claim 4, wherein the window further comprises a base layer,

wherein the strength reinforcing portion protrudes from the base layer to increase a thickness of the window at the corner.

7. The display device of claim 2, wherein the protective cover comprises:

a cover portion on a rear surface of the display module; and

a support portion extending from the cover portion and supporting the window.

8. The display device of claim 7, wherein the support portion comprises:

a bottom portion coupled to the cover portion; and

a support bar protruding from the bottom portion and having an upper end where a seating surface supports the window.

9. The display device of claim 7, wherein the protective cover further comprises a fixing portion that affixes the protective cover to the rear surface of the display module.

10. The display device of claim 9, wherein the fixing portion has a plate shape and faces the rear surface of the display module.

11. The display device of claim 10, wherein the protective cover further comprises a double-sided adhesive member that affixes the fixing portion to the rear surface of the display module.

12. The display device of claim 9, wherein the protective cover further comprises a connection portion extending from a side of the cover portion and coupling the fixing portion and the cover portion.

13. The display device of claim 1, wherein the stopper comprises a protruding portion protruding from the protective cover in a first direction parallel to a first periphery of the window,

wherein the window comprises a strength reinforcing portion provided on a corner of the window adjacent the first periphery.

14. The display device of claim 13, wherein the protruding portion overlaps the strength reinforcing portion, and is engaged with the strength reinforcing portion to limit a movement of the window.

15. The display device of claim 14, wherein the window further comprises a base layer,

wherein the strength reinforcing portion protrudes from the base layer to increase a thickness of the window at the corner.

16. The display device of claim 1, wherein the display module comprises:

a display panel on the rear surface of the window, and located to correspond with the first area and the second area; and

an input sensing unit between the window and the display panel.

17. The display device of claim 16, wherein the second area comprises:

a curvature area adjacent to the first area; and

a facing area adjacent to the curvature area and facing the first area.

18. The display device of claim 17, wherein the protective cover comprises:

a cover portion on a rear surface of the display module; and

a support portion extending from the cover portion and supporting the window.

19. The display device of claim 18, wherein the stopper is engaged with the window to maintain a first interval between the curvature area and the support portion.

20. A manufacturing method of an electronic device, the method comprising:

providing a display device including a window, a display module, a protective cover covering a portion of the display module and a stopper coupled with the protective cover;

removing the protective cover and the stopper from the display device; and

coupling the display module with components of an electronic device,

wherein the display module is disposed on a rear surface of the window and includes a first area and a second area configured to bend at a periphery of the non-bending area,

the protective cover is disposed on a rear surface of the display module to protect the bending area of the display module, and

the stopper is configured to limit a movement of the window.
