Display device

1. A display device comprising:

a display panel displaying an image;

an optical film disposed over the display panel and comprising a polarizer and at least one phase retarder;

a first adhesive layer disposed between the display panel and the optical film and contacting a first surface of the optical film; and

a second adhesive layer disposed on the optical film and contacting a second surface of the optical film opposite the first surface,

wherein each of the first adhesive layer and the second adhesive layer comprises a pressure sensitive adhesive, and at least one of the first adhesive layer and the second adhesive layer extends outside of a perimeter of the optical film such that the first adhesive layer and the second adhesive layer contact each other.

2. The display device of claim 1 , wherein at least one of the first adhesive layer and the second adhesive layer comprises a protrusion region protruding toward the outside of the optical film.

3. The display device of claim 2 , wherein the protrusion region surrounds the perimeter of the optical film.

4. The display device of claim 2 , wherein the display panel comprises a bending area bent around a bending axis extending in a direction, at least a portion of the optical film being in the bending area.

5. The display device of claim 4 , wherein the protrusion region comprises a first protrusion region and a second protrusion region spaced apart from each other in the direction in which the bending axis extends.

6. The display device of claim 2 , further comprising:

a window disposed over the optical film; and

a colored layer along an edge region of an inner surface of the window.

7. The display device of claim 6 , wherein at least one of the first adhesive layer and the second adhesive layer covers at least a portion of the colored layer.

8. The display device of claim 7 , wherein the protrusion region of the at least one of the first adhesive layer and the second adhesive layer has a thickness about three times to about fifty times greater than a thickness of the colored layer.

9. The display device of claim 2 , wherein the second adhesive layer comprises the protrusion region, the protrusion region covering an end of the optical film and an end of the first adhesive layer.

10. The display device of claim 9 , wherein the first adhesive layer has substantially a same area as that of the optical film.

11. The display device of claim 2 , wherein the first adhesive layer comprises the protrusion region, the protrusion region covering an end of the optical film and an end of the second adhesive layer.

12. The display device of claim 11 , wherein the second adhesive layer has substantially a same area as that of the optical film.

13. The display device of claim 2 , wherein each of the first adhesive layer and the second adhesive layer comprises the protrusion region, the protrusion region of the first adhesive layer contacting the protrusion region of the second adhesive layer at an outer edge of the optical film.

14. The display device of claim 1 , wherein the first adhesive layer and the second adhesive layer comprise a same material.

15. The display device of claim 1 , wherein the display panel comprises a display area and a non-display area, the display panel having an area greater than that of the optical film, and the optical film completely covers the display area.

16. The display device of claim 1 , wherein the pressure sensitive adhesive of each of the first adhesive layer and the second adhesive layer comprises an acryl-based adhesive or a silicon-based adhesive, and has a thickness of about 10 μm to about 500 μm.
