    摘要: A method of driving an active-matrix liquid-crystal display device includes a frame period of a picture displayed on a liquid-crystal panel divided into a scanning period and a hold period longer than the scanning period. In the scanning period, image data of an amount corresponding to a frame is written into the liquid-crystal panel. In the hold period following the scanning period, an off state is sustained. Each data line repeatedly experiences a positive-polarity frame period and a negative-polarity frame period, which are arranged alternately along the time axis. In a frame period, an electric potential appearing on a positive-polarity data line in the hold period is increased to a level higher than an electric potential appearing on an opposite electrode. The positive-polarity data line is defined as the data line, on which an electric potential appears at a level higher than an electric potential appearing on the opposite electrode.
