ABSTRACT:
An improved liquid crystal device which is driven by applying electric field thereon is shown. The device includes a ferroelectric liquid crystal layer which is separated into pixels and whose optical nature is changed by the electric field induced therein. Contiguous to the liquid crystal layer, a semiconductor charge storage layer is provided to give hysteresis to the device.
