Abstract:
A liquid crystal driving circuit is disclosed which carries out time-division driving with respect to each pixel constituting a liquid crystal display panel by causing a bright and dark frame period and a positive and negative frame period to be different from each other, the bright and dark frame period being a period of brightness and darkness of luminance at which to drive the each pixel, the positive and negative frame period being a period of polarities of a voltage to be applied to liquid crystal of the each pixel.
