Abstract

A display device includes: a display member; a cover window covering an upper portion of the display member and having a central portion and a curved portion; a lower cover covering a lower portion of the display member; a middle frame disposed between the cover window and the lower cover; a first coupling layer disposed between the curved portion of the cover window and the middle frame and made of an adhesive material; and a first filler filled in a space between the curved portion of the cover window and the display member, where at least a portion of the first coupling layer and the first filler overlap in a thickness direction of the display member.

Claims (38)

1 . A display device comprising:

a display member;

a cover window covering an upper portion of the display member and having a central portion and a curved portion;

a lower cover covering a lower portion of the display member;

a middle frame disposed between the cover window and the lower cover;

a first coupling layer disposed between the curved portion of the cover window and the middle frame and made of an adhesive material; and

a first filler filled in a space between the curved portion of the cover window and the display member,

wherein at least a portion of the first coupling layer and the first filler overlap in a thickness direction of the display member.

2 . The display device of claim 1 , wherein the curved portion becomes thinner as a distance from the central portion increases.

3 . The display device of claim 2 , wherein a slope of an outer wall of the curved portion is steeper than a slope of an inner wall.

4 . The display device of claim 2 , wherein the first coupling layer includes a first_first coupling layer in contact with the curved portion and a first_second coupling layer that is not in contact with the curved portion.

5 . The display device of claim 4 , wherein the middle frame, the first_second coupling layer, the first filler, and the cover window overlap in the thickness direction.

6 . The display device of claim 5 , wherein the first filler is in contact with the first_second coupling layer, the cover window, and a side surface of the display member.

7 . The display device of claim 6 , wherein the first filler is made of resin.

8 . The display device of claim 6 , wherein a thickness of the first filler is smaller than a height of an inner side of the cover window.

9 . The display device of claim 1 , wherein the display member includes a display panel on which an image is displayed, and

the display panel includes a bending area in which the display panel is bent.

10 . The display device of claim 9 , wherein a space the bending area of the display panel surrounds is filled with a second filler.

11 . The display device of claim 10 , wherein the second filler is formed of a same material as the first filler.

12 . The display device of claim 11 , wherein the second filler is made of resin.

13 . The display device of claim 9 , wherein the middle frame includes a middle plate disposed on a rear surface of the display panel, and a middle sidewall coupled to a side surface of the middle plate to vertically support the curved portion, and

the middle frame is disposed to be spaced apart from the display panel to include an accommodating space therebetween.

14 . The display device of claim 1 , further comprising a second coupling layer disposed between the middle frame and the lower cover and made of an adhesive material.

15 . The display device of claim 1 , wherein the cover window has a dome shape that is convex in the thickness direction.

16 . A display device comprising:

a display member;

a cover window covering an upper portion of the display member and having a central portion and a curved portion;

a lower cover covering a lower portion of the display member;

a middle frame disposed between the cover window and the lower cover;

a first coupling layer disposed between the curved portion of the cover window and the middle frame and made of an adhesive material; and

a first filler filled in a space between the curved portion of the cover window and the display member,

wherein the curved portion becomes thinner as a distance from the central portion increases.

17 . The display device of claim 16 , wherein a slope of an outer wall of the curved portion is steeper than a slope of an inner wall.

18 . The display device of claim 17 , wherein the first filler is in contact with the first coupling layer, the cover window, and a side surface of the display member.

19 . The display device of claim 16 , wherein the display member includes a display panel on which an image is displayed,

the display panel includes a bending area in which the display panel is bent, and

a space the bending area of the display panel surrounds is filled with a second filler.

20 . The display device of claim 16 , wherein the cover window has a dome shape that is convex in a thickness direction of the display member.
