description A driving method of a liquid crystal device for recording an image, the liquid crystal device including a liquid crystal layer having a cholesteric liquid crystal, a photoconductor layer accumulated on the liquid crystal layer, and electrodes, includes initializing an entire liquid crystal layer to a focal conic texture by applying a voltage exceeding a threshold value of transition from a planar texture to a focal conic texture, exposing the liquid crystal device imagewise while applying a voltage not exceeding a threshold value from the focal conic texture to a homeotropic texture upon non-exposure but exceeding the threshold value upon exposure and that provides bistability of the focal conic texture and the homeotropic texture with hysteresis upon non-exposure, and fixing a displayed image by releasing an application of voltage to change a part of the liquid crystal layer changed to the homeotropic texture to the planar texture.
