Abstract

A color filter substrate for liquid crystal displays and a method of fabricating the same are disclosed. The color filter substrate includes a transparent insulating substrate, a black matrix, a red color filter which includes red color resin and transparent conductive material, a green color filter which includes green color resin and the transparent conductive material, and a blue color filter which includes blue color resin and the transparent conductive material. On the transparent insulating substrate and having a plurality of openings; a red color filter on one of the openings of the black matrix, wherein the red color filter includes a red color resin and a transparent conductive material; a green color filter on a second of the plurality of openings of the black matrix, wherein the green color filter includes a green color resin and the transparent conductive material; and a blue color filter on a third of the plurality of openings of the black matrix, wherein the blue color filter includes a blue color resin and the transparent conductive material.

Claims (20)

1 . A color filter substrate for a liquid crystal display, comprising:

a transparent insulating substrate;

a black matrix on the transparent insulating substrate and having a plurality of openings;

a red color filter on one of the openings of the black matrix, wherein the red color filter includes a red color resin and a transparent conductive material;

a green color filter on a second another of the plurality openings of the black matrix, wherein the green color filter includes a green color resin and the transparent conductive material; and

a blue color filter on a third of the plurality of openings of the black matrix, wherein the blue color filter includes a blue color resin and the transparent conductive material.

2 . The color filter substrate as set forth in claim 1 , wherein the red color filter, the green color filter, and the blue color filter are connected to each other on an upper side of the black matrix.

3 . The color filter substrate as set forth in claim 1 , wherein each of the red color filter, the green color filter, and the blue color filter includes the transparent conductive material in a sintered powder form.

4 . The color filter substrate as set forth in claim 1 , wherein the transparent conductive material is indium tin oxide (ITO) or indium zinc oxide (IZO).

5 . The color filter substrate as set forth in claim 1 , wherein each of the red color filter, the green color filter, and the blue color filter includes about 5-35 wt % transparent conductive material.

6 . The color filter substrate as set forth in claim 1 , wherein each of the red color filter, the green color filter, and the blue color filter is formed to have in a thickness of about 1-2 μm.

7 . A method of fabricating a color filter substrate for a liquid crystal display, comprising:

providing a transparent insulating substrate;

forming a black matrix having a plurality of openings on the transparent insulating substrate; and

forming a red color filter, including a red color resin and a transparent conductive material, a green color filter including a green color resin and the transparent conductive material, and a blue color filter including a blue color resin and the transparent conductive material on the openings of the black matrix.

8 . The method as set forth in claim 7 , wherein the red color filter, the green color filter, and the blue color filter are connected to each other on an upper side of the black matrix.

9 . The method as set forth in claim 7 , wherein the red color filter, the green color filter, and the blue color filter include the transparent conductive material in a sintered powder form.

10 . The method as set forth in claim 7 , wherein the transparent conductive material is indium tin oxide (ITO) or indium zinc oxide (IZO).

11 . The method as set forth in claim 7 , wherein each of the red color filter, the green color filter, and the blue color filter includes 5-35 wt % transparent conductive material.

12 . The method as set forth in claim 7 , wherein each of the red color filter, the green color filter, and the blue color filter is formed in a thickness of 1-2 μm.
