Claim Text:
1. A method of manufacturing a color filter substrate for a liquid crystal display device, comprising: forming a black matrix on a substrate including a pixel region, the black matrix corresponding to a border portion between adjacent pixel regions; forming a color filter layer on the black matrix; forming a common electrode on the color filter layer; forming a photosensitive layer on the common electrode; exposing the photosensitive layer to light through a mask, the mask including a transmitting portion and a blocking portion; forming first patterns and a second pattern by developing the exposed photosensitive layer, the first patterns corresponding to the pixel region, and the second pattern corresponding to the black matrix, wherein the second pattern is wider than the first patterns; and forming ribs and a spacer by heat-treating the first patterns and the second pattern, wherein the spacer has a higher height than the ribs, wherein the color filter layer has a step due to the black matrix, and wherein the step has a height within a range of about 0.8 μm to about 0.9 μm.
