Abstract
A color filter substrate for a LCD device comprises a transparent substrate having a substantially flat surface, a black matrix, a color filters portion, an electrode, a plurality of spacers, and an alignment film. The color filter portion having a plurality of colored layers disposed on the transparent substrate. The plurality of spacers each having a first spacer member and a second spacer member, wherein the first spacer member and the second spacer member are formed by different layers in the shape of a parallel construction, and overlap and intersect at an angle such that each of the spacers has an uniform height.
