Abstract
A liquid crystal display device includes a driver circuit for outputting a charging voltage at a beginning of a horizontal scanning period and then a gray scale voltage corresponding to a display data to a video signal line. The liquid crystal display device is driven by inverting a polarity of the gray scale voltage on a pixel electrode with respect to a common voltage on a common electrode every N lines of scanning lines, where N≧2 and by making a first charging time of the charging voltage corresponding to a first line of N lines of the scanning lines scanned immediately after inversion of the polarity of the gray scale voltage different from a second charging time of the charging voltage corresponding to a second line of the N lines scanned immediately succeeding the first line.
