ABSTRACT:
A liquid crystal, particularly a ferroelectric liquid crystal, is interposed between an electroconductive member and an electric charge accepting member to form a liquid crystal device. In the first step of image formation, a uniform polarity of charge is imparted to the entirety or a part of the electric charge accepting member whereby the liquid crystal is uniformly oriented to its first stable state under a uniform electric field thus formed therethrough. In the second step, the reverse polarity of charges are given imagewise to the charge accepting member, whereby the liquid crystal is reoriented imagewise to the second stable state to form an image.
