Abstract

A resin composition for producing a color filter by an ink jet system contains (A) a colorant, (B) a binder resin and (c) a solvent having a boiling point of 245° C. or more at normal pressure, wherein the color filter is produced by discharging the above resin composition from an ink jet head into light transmitting regions on the surface of a transparent substrate having banks formed thereon to store the resin composition in the light transmitting regions defined by the banks; forming a pixel pattern by drying the resin composition stored in the light transmitting regions; and forming a protective layer to cover the pixel pattern.
