Abstract

An embodiment of the present disclosure provides a display device including a front member disposed on a front surface of a display panel and having curved areas and a planar area, a second adhesive layer disposed on a rear surface of the display panel, a first member disposed on the second adhesive layer, a second member disposed on the first member, a heat dissipation member disposed on the second member and having a width different from that of the front member, an encapsulation member encapsulating the heat dissipation member and including a first region and a second region and a third adhesive layer disposed on the heat dissipation member, wherein the curved areas are located at both ends of the front member along a width direction of the front member, wherein a width of the encapsulation member is less than or equal to a width of the front member.

Claims (33)

1 . A display device, comprising:

a front member disposed over a front surface of a display panel and having curved areas and a planar area;

a second adhesive layer disposed on a rear surface of the display panel;

a first member disposed on the first adhesive layer;

a second member disposed on the first member;

a heat dissipation member disposed over the second member and having a width different from a width of the front member;

an encapsulation member encapsulating the heat dissipation member and including a first region and a second region; and

a third adhesive layer disposed over the heat dissipation member,

wherein the curved areas are located at both ends of the front member along a width direction of the front member, and

wherein a width of the encapsulation member is different from the width of the front member.

2 . The display device of claim 1 , wherein the width of the encapsulation member is less than the width of the front member.

3 . The display device of claim 1 , wherein the heat dissipation member is encapsulated in the first region of the encapsulation member.

4 . The display device of claim 3 , wherein the second region of the encapsulation member includes a plurality of holes.

5 . The display device of claim 4 , wherein the plurality of holes are disposed side by side at a same interval between one another.

6 . The display device of claim 4 , wherein the plurality of holes each have a circular shape or a polygonal shape.

7 . The display device of claim 4 , wherein the third adhesive layer and the second member are in contact with each other in the plurality of holes.

8 . The display device of claim 1 , wherein the first member includes a metal.

9 . The display device of claim 1 , further comprising a first adhesive layer between the display panel and the front member.

10 . The display device of claim 1 , wherein the width of the heat dissipation member is smaller than the width of the front member.

11 . A display device, comprising:

a front member having a first portion and a second portion;

a display panel over a back surface of the front member;

a cushioning layer over the display panel;

a heat dissipation member over the cushioning layer, overlapping the first portion, and being offset from the second portion of the front member;

an adhesive layer over the heat dissipation layer; and

an encapsulation layer including a first part and a second part, the first part including a first layer and a second layer, the first layer between the heat dissipation member and the cushioning layer, the second layer between the heat dissipation member and the adhesive layer, and the second part between the cushioning layer and the adhesive layer without the heat dissipation member.

12 . The display device of claim 11 , wherein the encapsulation layer includes at least one hole in the second part, and wherein the cushioning layer and the adhesive layer are in contact with each other through the at least one hole.

13 . The display device of claim 12 , wherein the at least one hole includes a hole having a circular shape.

14 . The display device of claim 12 , wherein the at least one hole includes a hole having a polygonal shape.

15 . The display device of claim 11 , wherein the heat dissipation member includes graphite.

16 . The display device of claim 11 , wherein the first portion includes a planar portion and a curved portion, and

wherein the heat dissipation member overlaps the curved portion of the first portion.

17 . The display device of claim 16 , wherein the second portion is curved.
