ABSTRACT:
In a vertical retrace interval, a pre-charge potential or a signal potential is applied to each polarity for AC driving liquid crystal at least once each, so as to maintain fluctuations in pixel potential between the positive polarity side and the negative polarity side uniform, and minimum required potentials are supplied to the data signal line, thereby suppressing decrease in image quality without significantly increasing power consumption.
