Abstract

A display device includes a window panel over a display panel. The window panel includes a display area to transmit an image generated by the display panel and a non-display area adjacent the display area. The window panel includes a first light-shielding printed layer and first to third decor printed layers. The first light-shielding printed layer is in the non-display area. The first decor printed layer is in the non-display area and covers a side surface of the first light-shielding printed layer and at least a portion of an upper surface of the first light-shielding printed layer. The second decor printed layer is on the first light-shielding printed layer and the first decor printed layer. The second light-shielding printed layer is on the first light-shielding printed layer and the second decor printed layer.

First claim

What is claimed is:

1. A display device, comprising:
a display panel to display an image; and
a window panel over the display panel and including a display area to transmit the image and a non-display area adjacent the display area, wherein the window panel includes:
a substrate;
a first light-shielding printed layer on the susbtrate in the non-display area;
a first decor printed layer on the substrate in the non-display area and covering a side surface of the first light-shielding printed layer and at least a portion of an upper surface of the first light-shielding printed layer;
a second decor printed layer including a plurality of design layers on the first decor printed layer, at least one of the design layers overlapping the first light-shielding printed layer and another one of the design layers not overlapping the first light-shielding printed layer; and
a second light-shielding printed layer on the first light-shielding printed layer and the second decor printed layer, wherein the non-display area adjacent the display area includes a first non-display area around the display area and a second non-display area around the first non-display area, and wherein the first and the second light-shielding printed layers are disposed in the first non-display area.

2. The display device as claimed in claim 1 , wherein the first light-shielding printed layer and the first decor printed layer are on a same layer.

3. The display device as claimed in claim 1 , wherein a height of the first decor printed layer is greater than a height of the first light-shielding printed layer.

4. The display device as claimed in claim 1 , wherein the second decor printed layer is on a portion of the upper surface of the first light-shielding printed layer and a portion of a side surface of the first decor printed layer.

5. The display device as claimed in claim 1 , wherein the second light-shielding printed layer covers a side surface of the second decor printed layer.

6. The display device as claimed in claim 5 , wherein the second light-shielding printed layer covers a portion of an upper surface of the second decor printed layer and a portion of the upper surface of the first light-shielding printed layer.

7. The display device as claimed in claim 1 , wherein the second decor printed layer includes:
a first design layer on the first decor printed layer and the first light-shielding printed layer;
a second design layer on the first design layer; and
a third design layer on the second design layer.

8. The display device as claimed in claim 7 , wherein:
a width of the first design layer is greater than a width of the second design layer, and
the width of the second design layer is greater than a width of the third design layer.

9. The display device as claimed in claim 8 , wherein the first design layer is closer to the display area than the second design layer, and wherein the second design layer is closer to the display area than the third design layer.

10. The display device as claimed in claim 9 , wherein the first, second, and third design layers have a same color different from black.

11. The display device as claimed in claim 1 , wherein the light-shielding printed layers have a light shielding rate higher than the decor printed layers.

12. A method of manufacturing a display device, the method comprising:
providing a window panel including a non-display area adjacent to a display area;
forming a first light-shielding printed layer on a window substrate in the non-display area;
forming a first decor printed layer on the window substrate to cover a side surface of the first light-shielding printed layer and at least a portion of an upper surface of the first light-shielding printed layer, in the non-display area;
forming a second decor printed layer including a plurality of design layers on the first decor printed layer, at least one of the design layers overlapping the first light-shielding printed layer and another one of the design layers not overlapping the first light-shielding printed layer; and
forming a second light-shielding printed layer on the first light-shielding printed layer and the second decor printed layer, wherein the non-display area adjacent the display area includes a first non-display area around the display area and a second non-display area around the first non-display area, and wherein the first and the second light-shielding printed layers are disposed in the first non-display area.

13. The method as claimed in claim 12 , wherein a height of the first decor printed layer is greater than a height of the first light-shielding printed layer.

14. The method as claimed in claim 12 , wherein the second light-shielding printed layer covers a side surface of the second decor printed layer.

15. The method as claimed in claim 14 , wherein the second light-shielding printed layer covers a portion of an upper surface of the second decor printed layer and a portion of the upper surface of the first light-shielding printed layer.

16. The method as claimed in claim 12 , wherein forming the second decor printed layer includes:
forming a first design layer on the first decor printed layer and the first light-shielding printed layer;
forming a second design layer on the first design layer; and
forming a third design layer on the second design layer.

17. The method as claimed in claim 16 , wherein:
a width of the first design layer is greater than a width of the second design layer, and
the width of the second design layer is greater than a width of the third design layer.

18. The method as claimed in claim 17 , wherein the first design layer is closer to the display area than the second design layer, and wherein the second design layer is closer to the display area than the third design layer is to the display area.

19. The method as claimed in claim 18 , wherein the first, second, and third design layers have a same color different from black.

20. The method as claimed in claim 12 , wherein the light-shielding printed layers have a light shielding rate higher than the decor printed layers.
