Document Type and Number:
Japanese Patent JP2665477
Kind Code:
B2
Abstract:
A liquid crystal display element of optical writing type is arranged to have a first transparent substrate (11a), a first transparent electrode layer (12a) formed on the first substrate, a photoconductive layer (13) formed on the electrode layer, a light absorbing layer (14) formed on the photoconductive layer, a dielectric layer (16) formed on the light absorbing layer, a second transparent substrate (11b), a second transparent electrode layer (12b) formed on the second substrate, and a liquid crystal layer (17) 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 (15) formed on the light absorbing layer.
