摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates respectively having thereon a group of stripe-shaped scanning electrodes and a group of stripe-shaped data electrodes disposed to intersect the scanning electrodes and a liquid crystal 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 by applying a scanning selection signal sequentially to the scanning electrodes, and applying data signals to the data electrodes while phase modulating the data signals depending on given gradation data. One unit period of data signal is divided into plural sections, the data signals in each section are phase-modulated in one direction in accordance with an increase in gradation data, and the data signals in mutually adjacent sections are phase-modulated in mutually opposite directions in accordance with an increase in gradation data.
