Liquid crystal display element of optical writing type with light absorbing layer including inorganic pigment and leveling layer

Abstract

A liquid crystal display element of optical writing type is arranged to have a first transparent substrate, a first transparent electrode layer formed on the first substrate, a photoconductive layer formed on the electrode layer, a light absorbing layer formed on the photoconductive layer, a dielectric layer formed on the light absorbing layer, a second transparent substrate, a second transparent electrode layer formed on the second substrate, and a liquid crystal layer sealed between the second transparent electrode layer and the dielectric layer. The light absorbing layer is formed of a material having pigment dispersed in an organic material, so as to eliminate the necessity of patterning the light absorbing layer. The pigment may be a carbon black or an inorganic material in an acrylic resin, for example. The liquid crystal display element further includes a leveling layer formed on the light absorbing layer.
