Abstract

A display device includes a display panel including a bending area and a non-bending area adjacent to the bending area, a polarizing layer on the display panel and overlapping with the non-bending area, a support layer on the display panel and overlapping with the bending area, and an adhesive layer including a first adhesive portion between the non-bending area of the display panel and the polarizing layer and a second adhesive portion between the bending area of the display panel and the support layer.

Claims (41)

1. A display device comprising:

a display panel comprising a bending area and a non-bending area adjacent to the bending area;

a polarizing layer on the display panel and overlapping with the non-bending area;

a support layer on the display panel and overlapping with the bending area; and

an adhesive layer comprising a first adhesive portion between the non-bending area of the display panel and the polarizing layer, and a second adhesive portion between the bending area of the display panel and the support layer.

2. The display device of claim 1 , wherein the support layer and the polarizing layer are provided as an integrated shape and contacting each other.

3. The display device of claim 1 , wherein the second adhesive portion has a curved shape and is arranged over the entire bending area of the display panel, and

the support layer has a curved shape and is arranged over the entire second adhesive portion.

4. The display device of claim 3 , wherein each of the support layer and the second adhesive portion does not overlap with the non-bending area.

5. The display device of claim 1 , wherein the support layer has a same thickness as the polarizing layer.

6. The display device of claim 1 , wherein the display panel comprises:

a base substrate comprising a flat portion corresponding to the non-bending area and a bending portion bent from the flat portion and corresponding to the bending area;

a display element layer on the flat portion; and

an encapsulation layer on the display element layer,

wherein the first adhesive portion is between the encapsulation layer and the polarizing layer.

7. The display device of claim 6 , wherein the flat portion comprises a first flat portion and a second flat portion, which are spaced apart from each other in a thickness direction of the base substrate.

8. The display device of claim 7 , further comprising a protection layer between the first flat portion and the second flat portion to support the first flat portion.

9. The display device of claim 1 , wherein the first adhesive portion and the second adhesive portion are provided as an integrated shape, and

the first adhesive portion and the second adhesive portion have a same thickness as each other.

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

a window comprising a display area and a non-display area adjacent to the display area, and arranged on the polarizing layer; and

a window adhesive layer between the window and the polarizing layer,

wherein the bending area of the display panel entirely overlaps with the non-display area.

11. A display device comprising:

a display panel comprising a bending area and a non-bending area adjacent to the bending area;

a polarizing layer on the display panel and overlapping with the non-bending area;

a support layer comprising a first support portion on the display panel and overlapping with the non-bending area, and a second support portion on the display panel and overlapping with the bending area; and

an adhesive layer comprising a first portion between the display panel and the polarizing layer and overlapping with the non-bending area and a remaining portion between the display panel and the first support portion.

12. The display device of claim 11 , wherein the first portion of the adhesive layer has a planar area greater than that of the remaining portion of the adhesive layer.

13. The display device of claim 11 , wherein the second support portion has a curved shape and is arranged over the entire bending area of the display panel.

14. The display device of claim 13 , wherein the adhesive layer does not overlap with the bending area.

15. The display device of claim 11 , wherein the display panel comprises:

a base substrate comprising a flat portion corresponding to the non-bending area and a bending portion bent from the flat portion and corresponding to the bending area;

a display element layer on the flat portion; and

an encapsulation layer on the display element layer and overlapping with the flat portion,

wherein the first support portion is on the adhesive layer overlapping the flat portion, and the second support portion is on the bending portion.

16. The display device of claim 15 , wherein at least a portion of the second support portion is spaced apart from the display panel.

17. The display device of claim 11 , wherein the adhesive layer has a uniform thickness.

18. The display device of claim 11 , wherein the polarizing layer and the support layer are provided as an integrated shape.

19. The display device of claim 11 , wherein the support layer has a same thickness as the polarizing layer.

20. The display device of claim 11 , wherein the first support portion contacts the polarizing layer.
