    Abstract: A manufacturing method of a color filter, includes: forming a black matrix on a substrate; adding photosensitive pigment material into the black matrix to form color resist units; exposing each color resist unit, in which different areas of each color resist unit are irradiated with light of different intensity; and developing each color resist unit to form a color resistance. Since the adjoining areas of each color resistance that adjoin the black matrix are flatter than the adjoining areas of each color resist unit that adjoin the black matrix, therefore, the surface of the transparent conductive layer covering the adjoining areas of each color resistance is also correspondingly flatter than before, which allows the liquid crystal molecules in the transparent conductive layer to be regularly arranged to improve the contrast of the color filter layer.

A film that includes a carrier sheet and an imageable material is used to form a mask image that is opaque to a curing radiation. In one embodiment, the mask image is formed on the carrier sheet while in another embodiment, the mask image is formed on a receptor sheet. The mask image is then transferred to a photosensitive material, such as a flexographic printing plate precursor. The resulting assembly is exposed to the curing radiation resulting in exposed and unexposed areas of the photosensitive material. The carrier sheet or the receptor sheet may be removed from the mask image either before or after exposure to the curing radiation. Finally, the photosensitive material and mask image assembly is developed with a suitable developer to form a relief image.
