Abstract
A liquid crystal display device and driving method therefor are disclosed. The device includes a plurality of signal lines that apply different gray scale voltages to each of the pixels. A driving circuit is provided to generate the gray scale voltages to be applied to the pixels. In operation, the driving circuit applies the first gray scale voltage at intervals of the horizontal scanning time within a display period. The second gray scale voltage is output by a number of times that is not smaller than twice and not greater than (M-N) times at intervals of the horizontal scanning time from the beginning of the vertical retrace interval. The second gray scale voltage is then stopped until completion of the vertical retrace interval.
