发明名称 Voltage polarity switching means for cholesteric liquid crystal displays
摘要 A display device particularly adapted for use with a microfilm reader, in which an illuminating light source need be activated only in an initial reading stage. A first transparent electrode, a liquid crystal layer, a semiconductor layer and a second transparent electrode are stacked together in the stated order. A voltage is applied between the first and second transparent electrodes which is switched in a polarity between an initial reading mode and a display mode.
