Abstract

A display device includes a display panel comprises a display area and a non-display area surrounding the display area; a cover panel disposed on a rear surface of the display panel and comprising a front surface, a first side surface connected to the front surface and bent along a first bending line, a second side surface connected to the front surface and bent along a second bending line intersecting the first bending line, and a first corner located between the first side surface and the second side surface; and an alignment notch defined at the first corner of the cover panel.

Claims (27)

1. A display device comprising:

a display panel comprising a display area and a non-display area surrounding the display area; and

a cover panel disposed on a rear surface of the display panel and comprising a front surface, a first side surface connected to the front surface and bent along a first bending line, a second side surface connected to the front surface and bent along a second bending line intersecting the first bending line, and a first corner located between the first side surface and the second side surface,

wherein an alignment notch is defined at an outer end of the first corner of the cover panel in a plan view, and

the display panel covers an entirely of the alignment notch in the plan view.

2. The display device of claim 1 , wherein the alignment notch is defined to overlap the non-display area of the display panel in a thickness direction.

3. The display device of claim 2 , wherein the cover panel further comprises an alignment hole defined in the front surface.

4. The display device of claim 2 , wherein the display panel further comprises an alignment mark disposed in the non-display area.

5. The display device of claim 4 , wherein the cover panel is smaller than the display panel, and wherein an edge of the cover panel is disposed to overlap the non-display area of the display panel in the plan view.

6. The display device of claim 5 , wherein the edge of the cover panel is disposed further inside the display panel than the alignment mark in the plan view.

7. The display device of claim 4 , wherein a size of the alignment mark is smaller than a size of the alignment notch in a plan view.

8. The display device of claim 4 , wherein the alignment mark is disposed at a corner of the display panel.

9. The display device of claim 1 , wherein the alignment notch is defined across the first bending line and the second bending line.

10. The display device of claim 1 , wherein the alignment notch is defined in a center area of the first corner of the cover panel.

11. The display device of claim 10 , wherein the center area of the first corner comprises a corner of the front surface of the cover panel.

12. The display device of claim 1 , wherein the alignment notch is bent in a thickness direction.

13. The display device of claim 1 , wherein the first corner comprises a first double curvature portion curved with two or more curvatures, and wherein the alignment notch is defined at the first double curvature portion.

14. The display device of claim 13 , where the first corner comprises a first cutting line disposed between the first side surface and the first double curvature portion and a second cutting line disposed between the second side surface and the first double curvature portion, and wherein the alignment notch is defined between the first cutting line and the second cutting line.

15. The display device of claim 1 , wherein the cover panel further comprises a polymer film layer, a cushion member, and a heat dissipation member which are sequentially stacked on the rear surface of the display panel.

16. The display device of claim 15 , wherein the cover panel further comprises a first coupling member disposed between the display panel and the polymer film layer, a second coupling member disposed between the polymer film layer and the cushion member, and a third coupling member disposed between the cushion layer and the heat dissipation member.

17. The display device of claim 1 , wherein the cover panel further comprises: a third side surface connected to the front surface and bent along a third bending line, and a fourth side surface connected to the front surface and bent along a fourth bending line.

18. A display device comprising:

a display panel comprising a display area and a non-display area surrounding the display area;

a cover panel disposed on a rear surface of the display panel and comprising a front surface, a first side surface connected to the front surface and bent along a first bending line, a second side surface connected to the front surface and bent along a second bending line intersecting the first bending line, and a first corner located between the first side surface and the second side surface; and

an alignment notch defined at the first corner of the cover panel,

wherein the cover panel is smaller than the display panel, and

wherein an edge of the cover panel is disposed to overlap the non-display area of the display panel in a plan view.
