6. The display device of claim 5 ,

wherein the first barrier sheet includes a first barrier area overlapping the first support member, the folding area, and the second support member, and a second barrier area overlapping the second support member and not overlapping the first support member and the folding area in the plan view in the unfolding state.

7. The display device of claim 6 ,

wherein a width of the first barrier area is greater than a width of the second barrier area in a second direction crossing the first direction, and the second barrier area is disposed between second adhesive members.

8. The display device of claim 1 ,

wherein the second barrier sheet covers and overlaps entirety of the first barrier sheet, and has a greater planar area than the first barrier sheet in the plan view in the unfolding state.

9. The display device of claim 1 ,

wherein a maximum length of the second barrier sheet is greater than or equal to a maximum length of the first barrier sheet in the first direction.

10. The display device of claim 1 ,

wherein the second barrier sheet overlaps a portion of the first barrier sheet, and does not overlap a remaining portion of the first barrier sheet.

11. The display device of claim 10 , further comprising:

a third barrier sheet disposed in an area of a back surface of the first barrier sheet, not overlapping the second barrier sheet, and spaced apart from the second barrier sheet in the plan view in the unfolding state,

wherein the third barrier sheet and the second barrier sheet are disposed on a same plane.

12. The display device of claim 11 ,

wherein the third barrier sheet is attached to the back surface of the first barrier sheet through a third adhesive member disposed in an area of the back surface of the first barrier sheet, not overlapping the second barrier sheet in the plan view in the unfolding state.

13. The display device of claim 11 ,

wherein a gap between the third barrier sheet and the second barrier sheet does not overlap the folding area in the plan view in the unfolding state.

14. The display device of claim 13 ,

wherein the gap between the third barrier sheet and the second barrier sheet overlaps the first support member, and does not overlaps the second support member in the plan view in the unfolding state.

15. The display device of claim 1 ,

wherein one side of the first support member and one side of the second support member, which are adjacent to the folding area, face each other and have a hemming structure.

16. The display device of claim 1 , further comprising:

a connection unit disposed behind the second barrier sheet,

wherein the connection unit includes a first hinge bracket overlapping the first support member, a second hinge bracket overlapping the second support member, and a hinge structure coupling the first hinge bracket and the second hinge bracket, and

the hinge structure overlaps the first barrier sheet and the second barrier sheet in the plan view in the unfolding state.

17. A display device, comprising:

a display panel including a folding area, a first unfolding area and a second unfolding area, wherein the first and second unfolding areas are adjacent to each other with the folding area therebetween;

a first support member and a second support member disposed on a back surface of the display panel and spaced apart from each other with the folding area therebetween;

a first adhesive member disposed on a back surface of the first support member and a second adhesive member disposed on a back surface of the second support member;

a first barrier sheet at least partially fixed to the first adhesive member and extending to the back surface of the second support member; and

a second barrier sheet at least partially fixed to the second adhesive member, extending to the back surface of the first support member, and covering the first barrier sheet,

wherein the first barrier sheet and the second barrier sheet overlap a gap between the first support member and the second support member, and

the first barrier sheet is disposed between the second barrier sheet and the second support member and between the second barrier sheet and the first support member.

18. The display device of claim 17 , further comprising:

a hinge structure disposed behind the second barrier sheet,

wherein, when the display device is folded, the first barrier sheet and the second barrier sheet are bent according to a shape of an upper surface of the hinge structure.

19. The display device of claim 18 ,

wherein the upper surface of the hinge structure and the second barrier sheet at least partially contact each other, and the first barrier sheet and at least a portion of the second barrier sheet contact each other.

20. The display device of claim 17 ,

wherein one side of the first support member faces one side of the second adhesive member, and a length between one side of the first barrier sheet and one side of the second adhesive member in an unfolding state of the display device is shorter than and a length between one side of the first barrier sheet and one side of the second adhesive member in a folding state of the display device.
