Abstract

Claims (24)

1. A display device comprising:

a display panel comprising a folding area folded about a folding axis extending in a first direction, a first non-folding area, and a second non-folding area spaced apart from the first non-folding area with the folding area interposed therebetween in a second direction crossing the first direction;

a support member disposed on the display panel;

a first adhesive member disposed on the support member and overlapping the first non-folding area;

a second adhesive member disposed on the support member, overlapping the second non-folding area, and spaced apart from the first adhesive member in the second direction by a first gap; and

a heat dissipation member disposed on the support member and through which a first opening and a second opening are defined,

wherein, within a plane defined by the first direction and the second direction and including the first adhesive member and the second adhesive member, the first and second adhesive members are the only adhesive structures,

wherein a maximum value of the first gap corresponds to a distance between a center of the first non-folding area and a center of the second non-folding area,

wherein the first adhesive member and the second adhesive member extend only in a single column extending in the first direction,

wherein the first adhesive member has a first side and a second side opposed to each other in the first direction, the second adhesive member has a first side and a second side opposed to each other in the first direction, and the heat dissipation layer has a first side and a second side that are opposed to each other in the first direction,

wherein the first side of the first adhesive member and the first side of the second adhesive member are adjacent to the first side of the heat dissipation member, and

wherein the second side of the first adhesive member and the second side of the second adhesive member are adjacent to the second side of the heat dissipation member.

2. The display device of claim 1 ,

wherein the first adhesive member is disposed in the first opening, and the second adhesive member is disposed in the second opening.

3. The display device of claim 1 , wherein each of the first adhesive member and the second adhesive member has a bar shape.

4. The display device of claim 3 , wherein each of the first adhesive member and the second adhesive member is disposed substantially parallel to the first direction.

5. The display device of claim 1 , wherein each of the first adhesive member and the second adhesive member does not overlap the folding area, and the first gap is equal to or greater than about 35 millimeters and equal to or smaller than about 65 millimeters.

6. The display device of claim 1 , wherein the first adhesive member and the second adhesive member are symmetrical with each other with respect to the folding axis.

7. The display device of claim 1 , wherein the support member comprises:

a first support portion which overlaps the first non-folding area; and

a second support portion which is spaced apart from the first support portion and overlaps the second non-folding area.

8. The display device of claim 1 , wherein the support member comprises a support portion through which a plurality of openings is defined in an area corresponding to the folding area.

9. The display device of claim 1 , further comprising a cover member disposed under the first adhesive member and the second adhesive member.

10. The display device of claim 1 , wherein the heat dissipation member comprises graphite or a graphitized polymer.
