ABSTRACT:
A full-color liquid crystal display which is simple in construction and low in costs, also providing high quality of display performance. The liquid crystal display has a color filter substrate, an opposing substrate, and a liquid crystal charged between both the substrates. The color filter substrate includes a transparent substrate. A transparent electrode is mounted on one surface of the transparent substrate. A color filter is electro-deposited on the transparent electrode. A light-shielding film is formed in clearances provided for the color filter. An inorganic dielectric film is mounted on the surfaces of the color filter and the light-shielding film. A transparent electrode film is deposited on the dielectric film. On the other hand, the opposing substrate is constructed of a transparent substrate and a transparent electrode adhering to one surface of the substrate. As the liquid crystal, a nematic liquid crystal whose molecular longer axis is progressively twisted at 90.degree. between the transparent electrode films provided for the color filter substrate and the opposing substrate, respectively, is charged.
