Abstract

A display module including a display panel, a supporting member, a first circuit board, and a light blocking member. The display panel includes a display area and a non-display area. The non-display area is bent. The supporting member includes a first surface overlapping the display area; a second surface opposite to the first surface; and a third surface configured to connect the first surface to the second surface. The first circuit board faces the second surface and is electrically connected to the non-display area. The light blocking member contacts a bent area of the non-display area.

First claim

What is claimed is:

1. A display device, comprising:
a first display module including a first display area, a first non-display area adjacent to the first display area, a second non-display area bent from the first non-display area, and a curved surface overlapping the first non-display area; and
a second display module including a second display area, a third non-display area adjacent to the second display area, and a fourth non-display area bent from the third non-display area,
wherein the first non-display area overlaps the fourth non-display area where the curved surface and the fourth non-display area contact each other, and
wherein the first non-display area is substantially flat and partially surrounds the first display area, and the third non-display area is substantially flat and partially surrounds the second display area.

2. The display device of claim 1 , wherein the first display module comprises a first display panel comprising:
first upper and lower surfaces overlapping each of the first display area, the first non-display area, and the second non-display area;
a first side surface configured to connect the first upper surface and the first lower surface; and
the curved surface overlapping the first non-display area, wherein the curved surface is configured to connect the first lower surface and the first side surface; and
wherein the second display module comprises a second display panel comprising:
second upper and lower surfaces overlapping each of the second display area, the third non-display area, and the fourth non-display area; and
a second side surface configured to connect the second lower surface and the second upper surface,
wherein the curved surface is disposed on the second upper surface and overlaps the fourth non-display area.

3. The display device of claim 2 , wherein the first display module further comprises a first light blocking member disposed on the first display panel and overlapping the second non-display area, and a second light blocking member disposed on the first display panel and overlapping the first non-display area, and
the second display module further comprises a third light blocking member disposed on the second display panel and overlapping the third non-display area.

4. The display device of claim 3 , further comprising a fourth light blocking member disposed on the second display panel overlapping a portion of the fourth non-display area,
wherein the fourth light blocking member does not overlap the second light blocking member.

5. The display device of claim 2 , wherein the first display module further comprises a first supporting member overlapping the first display area and configured to support the first display panel, and
the second display module further comprises a second support member overlapping the second display area and configured to support the second display panel.

6. The display device of claim 5 , wherein the first display module further comprises a first circuit board disposed on a lower surface of the first supporting member and connected to the first display panel overlapping the second non-display area, and
the second display module further comprises a second circuit board disposed on a lower surface of the second supporting member and connected to the second display panel overlapping the fourth non-display area.

7. The display device of claim 2 , wherein the first display module further comprises a first protection film disposed on the first display panel and overlapping each of the first display area, the first non-display area, and
the second non-display area, and the second display module further comprises a second protection film disposed on the second panel and overlapping each of the second display area and the third non-display area.

8. The display device of claim 7 , wherein the first protection film is disposed above the second protection film in a thickness direction of the first display panel and the second display panel.

9. The display device of claim 7 , further comprising an adhesion member disposed on each of the first protection film and the second protection film; and
a window member disposed on the adhesion member.

10. The display device of claim 9 , wherein the adhesion member overlapping the first protection film has a thickness different from a thickness of the adhesion member overlapping the second protection member.

11. The display device of claim 2 , wherein the first display module further comprises a first input sensing member disposed on the first display area, and
the second display module further comprises a second input sensing member disposed on the second display area.
