Abstract:
A process for producing a filter comprising:a step of arranging an electrodeposition substrate, which comprises a light transmissible support having a light transmissible conductive film and a photosemiconductor thin film with a photoelectromotive function in this order provided thereon, in such a manner that at least said photosemiconductor thin film is immersed in an electrodeposition solution containing a colored electrodeposition material;a step of imagewise exposing said electrodeposition substrate with applying a voltage or an electric current to said conductive film, to form a colored electrodeposition film in an exposed part;a step of immersing at least said photosemiconductor thin film, on which said colored electrodeposition film has been formed, of said electrodeposition substrate in a metallic plating solution; anda step of applying a voltage or an electric current to said conductive film, to form a black matrix comprising a metallic plating film in a part of said photosemiconductor thin film, in which s aid colored electrodeposition film is not formed.
