Abstract

A display device including: a substrate configured to include a first region and a second region formed at an outer periphery of the first region; an emission layer disposed on the first region and the second region of the substrate; a polarizer disposed on the emission layer; a touch panel disposed on the polarizer; a window disposed on the touch panel; and a light blocking layer covering side surfaces of the polarizer and the touch panel and a top surface of the emission layer disposed on the second region of the substrate. The polarizer and the touch panel cover the first region of the substrate and expose the second region of the substrate.

Claims (28)

1. A display device comprising:

a substrate comprising a first region and a second region disposed at an outer periphery of the first region, wherein the first region is flat and the second region is upwardly-curved;

an emission layer comprising an organic light emitting element, the emission layer comprising a main emission layer disposed on the first region of the substrate and a dummy emission layer disposed on the second region of the substrate, the dummy emission layer comprising an upwardly-curving portion and a flat portion extending in a direction perpendicular to the main emission layer;

a polarizer disposed on the main emission layer;

a touch panel disposed on the polarizer;

a window disposed on the touch panel; and

a light blocking layer disposed on and covering side surfaces of the polarizer and the touch panel, and on a top surface of the dummy emission layer,

wherein the top surface of the flat portion of the dummy emission layer faces the side surface of the touch panel.

2. The display device of claim 1 , wherein the light blocking layer covers a side surface of the window.

3. The display device of claim 1 , wherein the light blocking layer comprises a light blocking film.

4. The display device of claim 1 , wherein the light blocking layer comprises a coated light blocking material.

5. The display device of claim 1 , wherein the light blocking layer comprises at least one of carbon black, carbon nanotubes, and chromium oxide.

6. The display device of claim 1 , wherein the second region of the substrate is bent such that an end portion thereof faces upwardly.

7. The display device of claim 1 , wherein the substrate is flexible.

8. The display device of claim 1 , further comprising a supporter configured to accommodate the substrate, the emission layer, the polarizer, the touch panel, and the window,

wherein a supporting surface of the supporter is bent and supports a bent portion of the second region.

9. A display device comprising:

a substrate comprising a first region and a second region disposed at an outer periphery of the first region, wherein the first region is flat and the second region is upwardly-curved;

an emission layer comprising an organic light emitting element, the emission layer comprising a main emission layer disposed on the first region of the substrate and a dummy emission layer disposed on the second region of the substrate, the dummy emission layer comprising an upwardly-curving portion and a flat portion extending in a direction perpendicular to the main emission layer;

a polarizer disposed on the main emission layer;

a touch panel disposed on the polarizer;

a window disposed on the touch panel; and

a light blocking member disposed in a space defined by side surfaces of the polarizer and the touch panel, and a top surface of the dummy emission layer,

wherein the top surface of the dummy emission layer faces the side surface of the touch panel.

10. The display device of claim 9 , further comprising a supporter configured to accommodate the substrate, the emission layer, the polarizer, the touch panel, and the window,

wherein a supporting surface of the supporter corresponds to a bending shape of the second region being formed therein so as to support the second region of the substrate.

11. The display device of claim 9 , wherein the substrate is flexible.

12. The display device of claim 9 , wherein the light blocking layer comprises of at least one of carbon black, carbon nanotubes, and chromium oxide.
