Patent ID: 8648984

Claim:
A color filter substrate for a liquid crystal display device, comprising: black matrixes on a transparent insulating substrate, the black matrixes defining pixel areas and having a first region and a second region, wherein the second region is a central portion of the black matrixes and a thickness of the black matrixes at the first region is greater than a thickness of the black matrixes at the second region; color filters in the pixel areas and having areas overlapping the first region of the black matrixes; a passivation layer on the black matrixes and the color filters; and ball spacers disposed only within the second region of the black matrixes, and contacted on a top surface of the passivation layer, the ball spacers being mixed with spacer ink droplets, wherein the black matrixes at the first region extend from the transparent insulating substrate to past a height of the top surface of the passivation layer at the second region where the ball spacers directly contact the passivation layer, whereby a thickness of the black matrixes at the first region is greater than a distance between the transparent insulating substrate and the top surface of the passivation layer at the second region.
