Abstract

A display device is disclosed. In one aspect, the display device includes a flexible display panel, and a first protection film attached to the flexible display panel and including a plurality of openings at least two of which have different sizes.

First claim

What is claimed is:

1 . A display device comprising:
a flexible display panel; and a first protection film attached to the flexible display panel and including a plurality of openings at least two of which have different sizes.

2 . The display device of claim 1 , wherein the first protection film has a mesh shape in a plane view.

3 . The display device of claim 1 , wherein the first protection film is thicker than the flexible display panel.

4 . The display device of claim 1 , wherein the first protection film includes an organic material.

5 . The display device of claim 1 , wherein the flexible display panel has a shape that is bent in one direction, and wherein the flexible display panel includes:
a first bending portion having a first curvature radius; and a second bending portion having a second curvature radius smaller than the first curvature radius.

6 . The display device of claim 5 , wherein the second bending portion is closer to a border of the flexible display panel than the first bending portion.

7 . The display device of claim 5 , wherein the openings include:
a first opening having a first size and overlapping the first bending portion in the depth dimension of the display device; and a second opening having a second size different from the first size and overlapping the second bending portion in the depth dimension of the display device.

8 . The display device of claim 7 , wherein the second size is larger than the first size.

9 . The display device of claim 5 , wherein the first protection film includes:
a first film portion having a first thickness, wherein the first film portion is formed on the same layer as the openings and overlaps the first bending portion in the depth dimension of the display device; and a second film portion having a second thickness different from the first thickness, wherein the second film portion is formed on the same layer as the first film portion and overlaps the second bending portion in the depth dimension of the display device.

10 . The display device of claim 9 , wherein the second thickness is less than the first thickness.

11 . The display device of claim 1 , further comprising:
a first adhesive layer positioned between the first protection film and the flexible display panel, wherein the first adhesive layer is positioned inside the openings.

12 . The display device of claim 1 , further comprising:
a second protection film attached to the first protection film and covering the openings.

13 . The display device of claim 12 , further comprising:
a second adhesive layer positioned between the first protection film and the second protection film, wherein the second adhesive layer is positioned inside the openings.

14 . The display device of claim 1 , further comprising:
a polarizer positioned over the first protection film via the flexible display panel; and a window positioned over the polarizer.

15 . A display device comprising:
a flexible display panel including a first bending portion and a second bending portion bent in one direction; and a first protection film attached to the flexible display panel and having first and second openings that have different sizes, wherein the first and second openings respectively overlap the first and second bending portions in the depth dimension of the display device.

16 . The display device of claim 15 , wherein the second bending portion has a smaller curvature radius than the first bending portion, and wherein the second opening is larger than the first opening.

17 . The display device of claim 16 , wherein the first film portion is formed on the same layer as the first opening and overlaps the first bending portion in the depth dimension of the display device, and wherein the second film portion is formed on the same layer as the first film portion and overlaps the second bending portion in the depth dimension of the display device, and wherein the first film portion is thinner than the second film portion.

18 . A display device comprising:
a flexible display panel; and a film assembly including a first protection film positioned over the flexible display panel, a first adhesive layer positioned between the first protection film and the flexible display panel, and the first protection film and a plurality of openings formed in at least one of the first adhesive layer and having different sizes.

19 . A display device comprising:
a flexible display panel; and a first protection film attached to the flexible display panel and including a plurality of grooves having different sizes from each other.

20 . A display device comprising:
a flexible display panel; and a first protection film attached to the flexible display panel and including a plurality of openings having different sizes from each other and a signal layer configured to receive a signal.
