Patent ID: 8264644

Claim:
A color filter substrate for an in-plane switching mode liquid crystal display device, comprising: a first rear side electrode on a first surface of a substrate and formed of a first transparent conductive material including zinc oxide (ZnO) and at least two compounds comprising second or fourth valence, the first rear side electrode comprising a first thickness; a black matrix comprising a lattice shape and a plurality of openings in the lattice shape, the black matrix disposed on a second surface, which is opposite to the first surface, of the substrate; a color filter layer in the plurality of openings; and an overcoat layer on the black matrix and the color filter layer, wherein the first transparent conductive material includes ZnO of about 94.95 to about 98.79 weight %, Al 2 O 3 of about 1 to about 3 weight %, Ga 2 O 3 of about 0.2 to about 2 weight %, and CaO of about 0.01 to about 0.05 weight %.
