Abstract

Claims (36)

1. A flexible display device comprising:

a display panel comprising a first non-bending area and a second non-bending area spaced apart along a first direction, and a bending area bent along a virtual bending axis extending along a second direction intersecting the first direction and disposed between the first non-bending area and second non-bending area;

a first protective member disposed on a lower surface of the display panel overlapping the first non-bending area and comprising a first inclined surface inclined from the lower surface; and

a second protective member disposed on the lower surface overlapping the second non-bending area and comprising a second inclined surface inclined from the lower surface and facing the first inclined surface, and

wherein the first inclined surface and the second inclined surface do not physically contact each other in a bending state of the bending area,

wherein a portion of the lower surface that overlaps at least a portion of the bending area is exposed between the first inclined surface and the second inclined surface, and

an angle between the portion and the first inclined surface and an angle between the portion and the second inclined surface are obtuse.

2. The flexible display device of claim 1 , wherein a space defined between the portion of the lower surface and the first and second protective members has a trapezoidal shape.

3. The flexible display device of claim 1 , further comprising an adhesive layer disposed on the lower surface and coupling the first protective member and the second protective member to the lower surface.

4. The flexible display device of claim 1 , wherein the first inclined surface and the second inclined surface have a step shape that is symmetrical to each other in cross section.

5. The flexible display device of claim 1 , wherein the first inclined surface and the second inclined surface have non-uniform surfaces.

6. The flexible display device of claim 1 , further comprising an outer member disposed on an upper surface of the display panel.

7. The flexible display device of claim 6 , wherein the outer member comprises at least one selected from a polarizer, a touch screen, and a protective member.

8. The flexible display device of claim 1 , wherein the first protective member and the second protective member are each a single layer.

9. The flexible display device of claim 1 , wherein a width of the first inclined surface and the second inclined surface in the first direction is 0.1 mm to 3 mm.

10. A flexible display device comprising:

a display panel comprising a first non-bending area and a second non-bending area spaced apart along a first direction, and a bending area bent along a virtual bending axis extending along a second direction intersecting the first direction and disposed between the first non-bending area and second non-bending area;

a first protective member disposed on a lower surface of the display panel overlapping the first non-bending area and comprising a first inclined surface inclined from the lower surface; and

a second protective member disposed on the lower surface overlapping the second non-bending area and comprising a second inclined surface inclined from the lower surface and facing the first inclined surface,

wherein the first inclined surface and the second inclined surface do not physically contact each other in a bending state of the bending area.

11. The flexible display device of claim 10 , wherein a portion of the lower surface that overlaps at least a portion of the bending area is exposed between the first inclined surface and the second inclined surface, and

an angle between the portion of the lower surface and the first inclined surface and an angle between the portion of the lower surface and the second inclined surface are obtuse.

12. The flexible display device of claim 10 , wherein the first inclined surface and the second inclined surface have a step shape that is symmetrical to each other in cross section.

13. The flexible display device of claim 10 , wherein the first inclined surface and the second inclined surface have non-uniform surfaces.

14. The flexible display device of claim 10 , further comprising an outer member disposed on an upper surface of the display panel, and

wherein the outer member comprises at least one selected from a polarizer, a touch screen, and a protective member.

15. A flexible display device comprising:

a display panel comprising a first flat area and a second flat area spaced apart along a first direction, and a bending area bent along a virtual bending axis extending along a second direction intersecting the first direction and disposed between the first flat area and second flat area;

a first protective member disposed on a lower surface of the display panel overlapping the first flat area;

a second protective member disposed on the lower surface overlapping the second flat area and spaced apart from the first protective member to expose the lower surface overlapping at least a portion of the bending area,

wherein a first inclined surface of the first protective member inclined from the lower surface and a second inclined surface of the second protective member inclined from the lower surface and facing the first inclined surface do not physically contact each other in a bending state of the bending area, and

wherein a portion of the lower surface that overlaps at least a portion of the bending area is exposed between the first protective member and the second protective member, and a space defined between the portion and the first and second protective members has a trapezoidal shape.

16. The flexible display device of claim 15 ,

wherein an angle between the portion and the first inclined surface and an angle between the portion and the second inclined surface are obtuse.

17. The flexible display device of claim 16 , wherein a width of the first inclined surface and the second inclined surface in the first direction is 0.1 mm to 3 mm.

18. The flexible display device of claim 16 , wherein the first inclined surface and the second inclined surface have non-uniform surfaces.
