Abstract

A window for a display device includes a display device window mother substrate; and a color layer on the display device window mother substrate. The color layer includes a transparent ink layer on the display device window mother substrate and including a pigment particulate, a solid color layer on the transparent ink layer, and a shield ink layer on the solid color layer.

First claim

What is claimed is:

1. A window for a display device, comprising
a display device window mother substrate; and
a color layer on the display device window mother substrate,
wherein the color layer comprises:
a transparent ink layer on the display device window mother substrate,
the transparent ink layer comprising a transparent ink in which a pigment particulate is disposed, the pigment particulate comprising a metal material,
a solid color layer on the transparent ink layer, and
a shield ink layer on the solid color layer.

2. The window for a display device of claim 1 , wherein the pigment particulate comprises a metal flake, pearl, mica, silica, or a combination thereof.

3. The window for a display device of claim 1 , wherein the solid color layer has a stacked structure comprising two or more layers.

4. The window for a display device of claim 1 , wherein the solid color layer comprises a combination of two or more color inks.

5. The window for a display device of claim 1 , wherein the display device window mother substrate comprises glass or a light-transmitting polymer resin.

6. The window for a display device of claim 5 , wherein the light transmitting polymer resin comprises polyethyleneterephthalate, polycarbonate, polymethylmethacrylate, a polycarbonate/polymethylmethacrylate copolymer, or a combination thereof.

7. The window for a display device of claim 1 , wherein the pigment particulate is included in the transparent ink layer at about 1 wt % to about 50 wt % based on a total weight of the transparent ink layer.

8. The window for a display device of claim 1 , wherein the display device window mother substrate has a cross-sectional thickness of about 300 micrometers to about 1000 micrometers.

9. The window for a display device of claim 1 , wherein the transparent ink layer has a cross-sectional thickness of about 4 micrometers to about 10 micrometers.

10. The window for a display device of claim 1 , wherein the solid color layer has a cross-sectional thickness of about 4 micrometers to about 10 micrometers.

11. The window for a display device of claim 1 , wherein the shield ink layer has a cross-sectional thickness of about 4 micrometers to about 10 micrometers.

12. The window for a display device of claim 1 , wherein an overall thickness of the window for the display device has a cross-sectional thickness of less than or equal to about 1 millimeter.

13. A method of manufacturing a window for a display device, comprising
preparing a display device window mother substrate, and
forming a color layer on the display device window mother substrate,
wherein the forming the color layer on the display device window mother substrate comprises:
disposing a pigment particulate in a transparent ink to form a transparent ink layer, the pigment particulate comprising a metal material,
forming a solid color layer on the transparent ink layer including the metal material pigment particulate in the transparent ink, and
forming a shield ink layer on the solid color layer.

14. The method of claim 13 , wherein the color layer is formed on the display device window mother substrate by a solution coating method or a film attachment method.

15. The method of claim 14 , wherein the solution coating method comprises spin coating, screen printing, pad printing, inkjet, printing one drop filling, or a combination thereof.

16. The method of claim 13 , wherein the pigment particulate comprises a metal flake, pearl, mica, silica, or a combination thereof.

17. The method of claim 13 , wherein the pigment particulate is included in the transparent ink layer at about 1 wt % to about 50 wt % based on a total weight of the transparent ink layer.

18. A display device comprising:
a window on a display module,
wherein the window comprises:
a display device window mother substrate; and
a color layer on the display device window mother substrate,
wherein the color layer comprises:
a transparent ink layer on the display device window mother substrate,
the transparent ink layer comprising a transparent ink in which a pigment particulate is disposed, the pigment particulate comprising a metal material,
a solid color layer on the transparent ink layer, and
a shield ink layer on the solid color layer.
