Display device

1. A display device comprising:

a display panel having a bending area; and

a protection film on a rear side of the display panel, the protection film comprising a first protection film and a second protection film, which are each a single layer, on respective sides of the bending area and separated from each other, the first protection film and the second protection film each having a slanted side adjacent to the bending area, the slanted sides being slanted with respect to the display panel when the display panel and the protection film are in a flat state.

2. The display device of claim 1 , wherein the first protection film and the second protection film each have a first side and a second side opposite to the first side, the first side being attached to the display panel, and the second side being wider than the first side.

3. The display device of claim 1 , wherein the display panel has a display area for displaying an image and a non-display area comprising a pad portion, the display area overlapping the first protection film, and the pad portion overlapping the second protection film.

4. The display device of claim 3 , wherein the bending area is in the non-display area.

5. The display device of claim 3 , further comprising a flexible printed circuit film connected to the pad portion.

6. The display device of claim 1 , wherein the protection film does not overlap the bending area.

7. The display device of claim 1 , wherein the protection film is below the display panel before the display panel is bent, and

wherein a cross-sectional shape of facing sides of each of the first protection film and the second protection film is substantially an inverted isosceles trapezoid.

8. The display device of claim 1 , wherein the slanted side of each of the first protection film and the second protection film is flat.

9. The display device of claim 1 , wherein the slanted side of each of the first protection film and the second protection film is curved.

10. The display device of claim 1 , wherein the protection film comprises polyethylene terephthalate, polyethylene naphthalate, polyimide, or polyethylene sulfide.

11. The display device of claim 1 , wherein the protection film has a thickness of about 50 to about 150 micrometers.

12. The display device of claim 1 , wherein the protection film is attached to the display panel by an adhesive layer.

13. The display device of claim 1 , wherein the display panel comprises a polarization layer, the polarization layer overlapping the first protection film and not overlapping the second protection film before the display panel is bent.

14. The display device of claim 1 , wherein each of the first protection film and the second protection film has a first side on the rear side of the display panel and a second side opposite the first side, and

wherein the slanted side of each of the first protection film and the second protection film is continuous from the first side to the second side thereof.

15. The display device of claim 1 , wherein:

the first protection film and the second protection film each have a first side attached to the display panel,

an angle between the slanted side and the first side of the first protection film is an obtuse angle, and

an angle between the slanted side and the first side of the second protection film is an obtuse angle.

16. The display device of claim 1 , wherein the slanted side of the first protection film does not contact the slanted side of the second protection film.
