Abstract
An improved liquid crystal device is shown. The device comprises a pair of substrates, a liquid crystal layer disposed inbetween and a pair of electrodes formed on the opposed insides of the substrate for applying an electric field on the liquid crystal layer. Further a dielectric film is formed on a inside of the substrate of the device. In response to an electric field applied to the liquid crystal layer, an electric charge is accumulated on the dielectric film to enable the device to exhibit apparent coersive electric field.
