A method of producing a color filter includes applying, on a semiconductor substrate, a first color filter material including a first resin dispersion including a first pigment and a resin material, curing the first color filter material such that a first color filter film is formed and serves as a precursor of a first color filter including the first pigment, forming a photosensitive resin mask material layer on the first color filter film, forming openings by photolithography in portions of the photosensitive resin mask material layer such that second and subsequent color filters including pigments of colors different from the first pigment are to be formed in the openings, and that portions of the first color filter film are exposed by the openings, dry-etching the portions of the first color filter film by using a dry etching gas and the photosensitive resin mask material layer as an etching mask, removing the etching mask such that the first color filter is formed, and forming the second and subsequent color filters.
