Abstract

A liquid crystal display device is proposed which has a substrate having electrodes corresponding to the display picture elements, liquid crystal arranged on the substrate through a dielectric mirror, and a transparent electrode arranged on liquid crystal and applying electric fields to the liquid crystal for each picture element through the respective electrodes on the substrate. The substrate has memory cells which are capable of storing data and of becoming electrically conductive, this conductive condition being determined and sustained based on the contents of the stored data. The electric fields are applied to the liquid crystal through these memory cells.
