Abstract
Disclosed is a method for driving a liquid crystal display unit, in particular, a method for driving an active matrix type liquid crystal display unit using a thin-film transistor as a switching element. According to the drive method, a plurality of scanning signal power voltages of which levels vary in synchronization with inversion in polarity of an image signal are input to a scanning signal supply circuit, and any of the plural scanning signal power voltages is selected to serve as a scanning signal. Otherwise, some scanning signal power voltages of which levels vary in synchronization with inversion in polarity of the image signal and some scanning signal power voltages of which levels are invariable are input to the scanning signal supply circuit, and any of the plural scanning signal power voltages is selected to serve as a scanning signal.
