Patent ID: 8034517

Claim:
A manufacturing method of a color filter, comprising: providing a transparent substrate; forming a black matrix on the transparent substrate to define a plurality of pixel areas on the transparent substrate; forming a layer of photosensitive material on the transparent substrate; patterning the layer of photosensitive material to form a patterned isolation layer on the black matrix; filling a plurality of color pigments in the pixel areas respectively; drying the color pigments to form a plurality of color filter units, wherein the film thickness of the color filter units is substantially same as the film thickness of the black matrix; and patterning the patterned isolation layer to remove a portion of the patterned isolation layer and form at least one pillared spacer on the black matrix, wherein a sum of the height of the pillared spacer and the film thickness of the black matrix is bigger than or equal to double of the film thickness of the color filter units.
