Color filter substrate and fabricating method thereof
View Patent ↗A color filter substrate includes a substrate, a black matrix that defines cell areas on a substrate and prevents light leakage, a color filter formed in the cell areas defined by the black matrix, and a conductive thin film formed on the rear surface of the substrate for preventing the generation of static electricity, wherein the conductive thin film is formed of a photo-resist containing a conductive material.
1. A color filter substrate, comprising:
a substrate having a front surface and a rear surface, the rear surface being etched;
a black matrix that defines cell areas on the front surface of the substrate and prevents light leakage;
a color filter formed in the cell areas defined by the black matrix;
a conductive thin film formed on the rear surface of the substrate for preventing the generation of static electricity;
an overcoat layer having a planar surface covering a step difference formed by the color filter and formed of polydimethylsiloxane: and
a spacer formed on the overcoat layer for maintaining a cell gap and formed of the same material as the overcoat layer,
wherein the conductive thin film is formed of a photo-resist containing a carbon nano tube; and
wherein the conductive thin film is formed by coating a liquid photo-resist containing the carbon nano tube and heating the coated liquid photo-resist containing the carbon nano tube.
2. The color filter substrate according to claim 1 , further comprising an alignment film formed on the overcoat layer for aligning liquid crystal molecules in a designated direction.
