<p>A liquid crystal device is formed by a plurality of scanning electrodes, a plurality of data electrodes intersecting the scanning electrodes, and a bistable liquid crystal showing a first stable orientation state and a second stable orientation state disposed between the scanning electrodes and the data electrodes so as to form a pixel at each intersection of the scanning electrodes and the data electrodes. The liquid crystal device is driven according to a scheme wherein a pixel is written in a first orientation state (or at a gradation level k) in two steps including: a first step of applying a prescribed voltage for causing the second orientation state to the pixel and then applying a voltage of at least V1 (or a voltage Va) to the pixel, and a second step of applying a voltage of at least V2 (or a voltage Vb) to the pixel, wherein V1 (Va) denotes a threshold voltage required for converting a pixel in the second orientation state into the first orientation state (into the gradation level k) after applying the prescribed voltage for causing the second orientation state to the pixel in the first orientation state, and V2 (Vb) denotes a threshold voltage required for converting a pixel in the second orientation state into the first orientation state (into the gradation level k) after applying the prescribed voltage for causing the second orientation state to the pixel in the second orientation state. <IMAGE></p> |
