<p>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 kept applied to the non-display unit area to maintain a uniform white or black display state. Durability of the non-display unit is particularly demanded. In this invention, however, the non-display unit includes first and second stripe electrodes 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. <IMAGE></p> |
