Abstract

A display device includes a flexible display module and a support member located below the flexible display module. The support member includes a first support member and a second support member. A portion of each of the first support member and the second support member, which is adjacent to a bending axis, is bent to have a curvature.

First claim

What is claimed is:

1. A display device comprising:
a flexible display module comprising a first display area and a second display area adjacent to the first display area, the flexible display module being foldable with respect to a boundary line between the first display area and the second display area; and
a support member comprising a first support member overlapping with the first display area and a second support member adjacent to the first support member and overlapping with the second display area, the support member being located below the flexible display module,
wherein the first support member comprises:
a first base support portion;
a first connection support portion extending from the first base support portion, located adjacent to the boundary line, and bent to have a curvature; and
a first extension support portion extending from the first connection support portion and overlapping with the first base support portion,
the second support member comprises:
a second base support portion;
a second connection support portion extending from the second base support portion, located adjacent to the boundary line, and bent to have a curvature; and
a second extension support portion extending from the second connection support portion and overlapping with the second base support portion, and
the first connection support portion is separate and spaced apart from the second connection support portion, and the first extension support portion is separate and spaced apart from the second extension support portion.

2. The display device of claim 1 , further comprising an impact absorbing member between the flexible display module and the support member.

3. The display device of claim 2 , further comprising an adhesion member comprising a first adhesion member and a second adhesion member, the adhesion member being between the impact absorbing member and the support member,
wherein the first base support portion is coupled to the impact absorbing member by the first adhesion member, and the second base support portion is coupled to the impact absorbing member by the second adhesion member.

4. The display device of claim 3 , wherein at least a portion of the first connection support portion, the first extension support portion, at least a portion of the second connection support portion, and the second extension support portion are spaced apart from the adhesion member.

5. The display device of claim 4 , wherein the first adhesion member is spaced apart from the second adhesion member.

6. A display device comprising:
a flexible display module comprising a first display area and a second display area adjacent to the first display area, the flexible display module being foldable with respect to a boundary line between the first display area and the second display area; and
a support member comprising a first support member overlapping with the first display area and a second support member overlapping with the second display area, the support member being located below the flexible display module,
wherein the first support member comprises:
a first base support portion;
a first connection support portion extending from the first base support portion, located adjacent to the boundary line, and bent to have a curvature; and
a first extension support portion extending from the first connection support portion and overlapping with the first base support portion,
the second support member comprises:
a second base support portion;
a second connection support portion extending from the second base support portion, located adjacent to the boundary line, and bent to have a curvature; and
a second extension support portion extending from the second connection support portion and overlapping with the second base support portion, and
the display device further comprises:
an impact absorbing member between the flexible display module and the support member; and
an adhesion member comprising a first adhesion member and a second adhesion member, the adhesion member being between the impact absorbing member and the support member,
wherein the first base support portion is coupled to the impact absorbing member by the first adhesion member, and the second base support portion is coupled to the impact absorbing member by the second adhesion member,
wherein at least a portion of the first connection support portion, the first extension support portion, at least a portion of the second connection support portion, and the second extension support portion are spaced apart from the adhesion member,
wherein the first adhesion member is spaced apart from the second adhesion member, and
wherein the adhesion member further comprises a third adhesion member between the first adhesion member and the second adhesion member, and a fourth adhesion member spaced apart from the third adhesion member.

7. The display device of claim 6 , wherein the third adhesion member is coupled to only one surface of the first support member, and the fourth adhesion member is coupled to only one surface of the second support member.

8. The display device of claim 7 , wherein each of the third adhesion member and the fourth adhesion member has a black color.

9. The display device of claim 3 , further comprising a housing configured to accommodate the flexible display module, the impact absorbing member, the adhesion member, and the support member,
wherein the housing supports the first base support portion and the second base support portion, and
the first connection support portion and the second connection support portion are accommodated in a space defined in the housing.

10. The display device of claim 9 , wherein, when the flexible display module is folded with respect to the boundary line, the first connection support portion and the second connection support portion are spaced apart from the housing.

11. The display device of claim 1 , wherein at least a portion of a surface of the first base support portion contacts at least a portion of a surface of the first extension support portion, and
at least a portion of a surface of the second base support portion contacts at least a portion of a surface of the second extension support portion.

12. The display device of claim 1 , wherein each of the first extension support portion and the second extension support portion is bent to have a curvature,
wherein the first extension support portion is spaced apart from the first base support portion, and the second extension support portion is spaced apart from the second base support portion.

13. The display device of claim 1 , wherein the first base support portion has a same area as that of the first extension support portion, and the second base support portion has a same area as that of the second extension support portion.

14. The display device of claim 1 , wherein the first base support portion has an area greater than that of the first extension support portion, and the second base support portion has an area greater than that of the second extension support portion.

15. The display device of claim 1 , wherein each of the first support member and the second support member comprises a metal.

16. The display device of claim 1 , wherein the flexible display module comprises a plurality of pixels each comprising a light emitting element, and a driving circuit configured to provide a data signal to the plurality of pixels, wherein the driving circuit is below the support member.

17. A display device comprising:
a flexible display module comprising a flexible display panel and an input sensi
