摘要： Each pixel of a liquid crystal display device comprises a switching device for selecting a data signal, a memory portion for storing the data signal selected by the switching device and outputting an analog signal corresponding to the data signal, and a circuit for supplying an AC voltage corresponding to the analog signal to the liquid crystal layer. The liquid crystal layer is driven with a data signal stored in the memory portion or with an AC voltage corresponding to an analog signal corresponding to the data signal. With the signal stored in the memory portion, an AC voltage whose effective value or average value is controlled is supplied to the liquid crystal layer. Thus, unless a picture on the display is changed, since it is not necessary to supply the data signal, the peripheral driving circuit can be stopped. Consequently, although a picture is displayed in gradation mode, the power consumption can be remarkably reduced.
