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.

First claim

What is claimed is:

1 . A method of fabricating a display device comprising:
preparing a cover panel 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; recognizing, by a detector, an alignment notch defined at a corner of the cover panel between the first side surface and the second side surface of the cover panel; aligning the cover panel; and assembling the cover panel and the display panel.

2 . The method of claim 1 , further comprising:
recognizing, by the detector, an alignment mark disposed at a corner of the display panel after the preparing of the display panel and the cover panel.

3 . The method of claim 1 , wherein the display panel comprises a display area and a non-display area surrounding the display area, and
wherein the display panel further comprises an alignment mark disposed in the non-display area.

4 . The method of claim 3 , wherein the cover panel is smaller than the display panel.

5 . The method of claim 4 , wherein an edge of the cover panel is disposed further inside the display panel than the alignment mark.

6 . The method of claim 3 , wherein a size of the alignment mark is smaller than a size of the alignment notch.

7 . The method of claim 1 , wherein the alignment notch is defined across the first bending line and the second bending line.

8 . The method of claim 1 , wherein the alignment notch is defined in a center area of the corner of the cover panel.

9 . The method of claim 8 , wherein the center area of the corner comprises a corner of the front surface of the cover panel.

10 . The method of claim 1 , wherein the alignment notch is bent in a thickness direction.

11 . The method of claim 1 , wherein the corner of the cover panel 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.

12 . The method of claim 11 , where the corner of the cover panel 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.

13 . The method 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.

14 . The method 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.

15 . The method of claim 1 , further comprising:
recognizing, by the detector, a virtual alignment mark defined by virtual extending lines of the cover window having the display panel attached thereto after the preparing of the display panel and the cover panel.

16 . The method of claim 1 , further comprising:
recognizing, by the detector, an alignment hole defined in the front surface of the cover panel after the preparing of the display panel and the cover panel.
