Abstract

A flexible display device includes a first non-bending area, a second non-bending area spaced apart from the first non-bending area, and a bending area between the first non-bending area and the second non-bending area; and a protective member on a surface of the flexible display panel, and including a first protective member overlapping the first non-bending area and a second protective member overlapping the second non-bending area, each of the first protective member and the second protective member including an inclined surface inclined with respect to the surface of the flexible display panel overlapping the flat area adjacent to the bending area, and the inclined surfaces do not physically contact each other in a bending state.

Claims (36)

1. A flexible display device comprising:

a flexible display panel comprising a first non-bending area, a second non-bending area spaced apart from the first non-bending area, and a bending area between the first non-bending area and the second non-bending area; and

a protective member on a surface of the flexible display panel, and comprising a first protective member overlapping the first non-bending area and a second protective member overlapping the second non-bending area;

wherein each of the first protective member and the second protective member comprises an inclined portion inclined with respect to the surface of the flexible display panel,

a portion overlapping the bending area of the surface of the flexible display panel is exposed between the inclined portions,

the bending area is bent along a virtual bending axis in a bending state, and a space defined by the portion and the inclined portions spaced apart from each other has a trapezoidal shape in a non-bending state, and

respective inclined surfaces of the inclined portions do not physically contact each other in the bending state.

2. The flexible display device of claim 1 , wherein each of the inclined portions is inclined at an acute angle with respect to the surface of the flexible display panel.

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

4. The flexible display device of claim 1 , further comprising an adhesive member between the flexible display panel and the protective member to bond the flexible display panel and the protective member.

5. The flexible display device of claim 1 , further comprising a touch screen on another surface of the flexible display panel facing away from the surface of the flexible display panel.

6. The flexible display device of claim 5 , further comprising an adhesive member between the touch screen and the flexible display panel to bond the touch screen and the flexible display panel.

7. The flexible display device of claim 5 , further comprising a polarizing plate on the touch screen.

8. A flexible display device comprising:

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

a protective member on a surface of the flexible display panel, and comprising a first protective member and a second protective member;

wherein the first protective member and second protective member are spaced apart from each other and expose a portion of the bending area;

wherein each of the first protective member and the second protective member comprises an inclined portion inclined with respect to the surface of the flexible display panel overlapping the non-bending area adjacent to the bending area,

the bending area is bent along a virtual bending axis in a bending state, and an angle between the portion and the respective inclined portion is an obtuse angle in a non-bending state, and

respective inclined surfaces of the inclined portions do not physically contact each other in the bending state.

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

10. The flexible display device of claim 8 , further comprising an adhesive member between the flexible display panel and the protective member to bond the flexible display panel and the protective member.

11. The flexible display device of claim 8 , further comprising a touch screen on another surface of the flexible display panel facing away from the surface of the flexible display panel, and

an adhesive member between the touch screen and the flexible display panel to bond the touch screen and the flexible display panel.

12. The flexible display device of claim 11 , further comprising a polarizing plate on the touch screen.

13. A flexible display device comprising:

a flexible display panel comprising a bending area and a flat area adjacent to the bending area; and

a protective member on a surface of the flexible display panel, and comprising a first protective member and a second protective member;

wherein the first protective member and second protective member are spaced apart from each other and expose a portion of the bending area,

wherein each of the first protective member and the second protective member comprises an inclined surface inclined with respect to the surface of the flexible display panel overlapping the flat area adjacent to the bending area, and

wherein the inclined surfaces do not physically contact each other in a bending state.

14. The flexible display device of claim 13 , wherein the first protective member and the second protective member are each a single layer.

15. The flexible display device of claim 13 , further comprising an adhesive member between the flexible display panel and the protective member to bond the flexible display panel and the protective member.

16. The flexible display device of claim 13 , further comprising a touch screen on another surface of the flexible display panel facing away from the surface of the flexible display panel, and

an adhesive member between the touch screen and the flexible display panel to bond the touch screen and the flexible display panel.

17. The flexible display device of claim 16 , further comprising a polarizing plate on the touch screen.
