1. A liquid crystal display device, comprising:
pixels equipped with a liquid crystal cell and a switch element, which are arranged at positions where scan lines and data
lines intersect;
a data line drive circuit for supplying, from said data line and said switch element to said liquid crystal cell, a write
signal corresponding with image data;
a control circuit for inverting a polarity of said write signal after every plurality of scan lines; and
a scan line drive circuit which supplies a drive signal to said scan lines and switches said switch elements ON and OFF, while
maintaining a constant horizontal scanning period, so that, of the plurality of scan lines to which is supplied a write signal
of a same polarity, in following scan lines other than those scan lines where the polarity of said write signal is inverted,
said drive signal is supplied for a period of time that is shorter, by a predetermined amount of time, than a time for which
said drive signal is supplied to scan lines where the polarity of said write signal is inverted.
