ABSTRACT A liquid crystal display device utilizing a ferro-electric liquid crystal, e.g., a chiral smectic liquid crystal aligned to establish two bi-stable display states. The display device is driven in a time-sharing mode. The change of the bi-stable display states is effected by applying a selected voltage to the changed ferro-electric liquid crystal. Thereafter the display state is held by applying an AC pulse voltage.
