Abstract
A brighter active matrix type liquid crystal electro-optical device with a higher contrast, yet having a wider visual angle is realized, said liquid crystal electro-optical device comprises a liquid crystal layer and means for applying an electric field to the liquid crystal layer in the direction parallel to the substrate, wherein the liquid crystal layer comprises a liquid crystal material dispersed in a polymer material. Also a liquid crystal electro-optical device comprising a liquid crystal layer disposed on a substrate is included, wherein the transmission mode or the dispersion mode of an incident light is selected by an electric field applied to the liquid crystal layer in the direction parallel to the liquid crystal layer.
