After forming a black matrix which defines pixel regions on a substrate, dyed substrate layers of photo hardening property are formed. By irradiating ultraviolet rays to the dyed substrate layers from the back of the substrate and by developing, ink reservoirs which use the black matrix as partition walls are formed. The dyeing material such as the dye is supplied to these ink reservoirs by an ink jet system. Due to these partition walls, there is no possibility that the dyeing material scatters to the neighboring or adjacent pixel regions to cause the mixed color. Further, since the filters having a sufficient thickness can be formed in the ink reservoirs, the surface flatness of the color filters can be sufficiently ensured without coating the thick overcoat layer.
