Abstract

There is provided a display device including a display panel configured to display an image, a window above the display panel and including a display area configured to transmit an image therethrough, a non-display area around the display area, a window base facing the display panel, a printed layer below the window base, and a low refractive-index zone between the window base and the printed layer, and an adhesive layer between the display panel and the window.

First claim

What is claimed is:

1. A display device comprising:
a display panel configured to display an image;
a window above the display panel and having a display area configured to transmit an image therethrough and a non-display area around the display area, the window comprising:
a window base facing the display panel;
a printed layer below the window base; and
a low refractive-index zone between the window base and the printed layer; and

an adhesive layer between the display panel and the window,
wherein the printed layer is at the non-display area, and contacts the adhesive layer.

2. The display device of claim 1 , wherein the low refractive-index zone comprises an air layer.

3. The display device of claim 1 , wherein the window further comprises a base film between the window base and the printed layer.

4. The display device of claim 3 , wherein the window further comprises an optically clear adhesive (“OCA”) layer between the window base and the base film.

5. The display device of claim 4 , wherein the low refractive-index zone is at a same layer as the OCA layer.

6. The display device of claim 4 , wherein the low refractive-index zone is above the OCA layer.

7. The display device of claim 1 , wherein the low refractive-index zone is between the display panel and the adhesive layer.

8. The display device of claim 7 , wherein the low refractive-index zone covers an entire surface of the adhesive layer.

9. The display device of claim 1 , wherein the low refractive-index zone comprises a material having a low refractive index.

10. The display device of claim 1 , further comprising a light absorbing member on a side surface of the window.

11. The display device of claim 10 , wherein the light absorbing member comprises a base resin, a light absorbing material, and a UV-curing accelerator.

12. A display device comprising:
a display panel configured to display an image;
a window above the display panel and having a display area configured to transmit an image therethrough and a non-display area around the display area, the window comprising:
a window base facing the display panel;
a printed layer below the window base; and
a low refractive-index zone between the window base and the printed layer; and

an adhesive layer between the display panel and the window,
wherein the printed layer comprises a first decor printed layer, and a light blocking printed layer.

13. The display device of claim 12 , wherein the light blocking printed layer contacts the adhesive layer.

14. The display device of claim 12 , wherein the first decor printed layer comprises a white printed layer.

15. The display device of claim 12 , wherein the light blocking printed layer comprises a black printed layer.

16. A display device comprising:
a display panel configured to display an image;
a window above the display panel and having a display area configured to transmit an image therethrough and a non-display area around the display area, the window comprising:
a window base facing the display panel;
a printed layer below the window base; and
a low refractive-index zone between the window base and the printed layer; and

an adhesive layer between the display panel and the window,
wherein the display panel comprises:
a first substrate;
a capping layer on the first substrate; and
a thin film encapsulation (“TFE”) layer on the capping layer.

17. The display device of claim 16 , further comprising a polarizer on the TFE layer, and facing the window base.

18. The display device of claim 17 , wherein the adhesive layer is between the polarizer and the window.

19. The display device of claim 17 , further comprising a touch screen panel (“TSP”) on the polarizer.
