Abstract:
1. A driving method of a liquid crystal display device having a plurality of pixels, a plurality of signal lines which apply a gray scale voltage to each of the pixels, and a driving circuit which outputs the gray scale voltage to each of the signal lines, comprising the steps of: outputting the gray scale voltage from the driving circuit to each of the signal lines by a number of times not smaller than twice and not greater than (M−N) times from the beginning a vertical retrace interval, where M represents a value obtained by dividing the vertical retrace interval by a horizontal scanning time and rounding up fractions to the nearest whole number, and N represents an integer not smaller than one; and thereafter stopping the outputting of the gray scale voltage from the driving circuit to each of the signal lines until completion of the vertical retrace interval; wherein an interval from a last outputting of the gray scale voltage within the vertical retrace interval until a first outputting of the gray scale voltage at a next frame is longer than the horizontal scanning time.
