ABSTRACT:
A technique for driving a liquid crystal apparatus having an effective display area and a non-display unit area is provided. When a bistable liquid crystal element is used, a voltage must be continuously applied to the non-display unit area to maintain a uniform white or black display state. Durability of the non-display unit is particularly desired. In this invention, the non-display unit includes first and second stripe electrodes disposed perpendicular to each other. First and second drive bipolar pulses are respectively applied to the first and second stripe electrodes with a phase difference between these bipolar pulses.
