ABSTRACT:
A liquid crystal display apparatus is provided with a detecting section (108) for detecting a value of a parameter that causes fluctuations in a back transition occurrence condition; a calculating section (106) for determining, in accordance with the detection value of the detecting section, at least one of a ratio of an time period of applying a high voltage with respect to one frame period, the high voltage being applied to the liquid crystal panel in order to prevent back transition, a magnitude of the high voltage, and an applied voltage corresponding to white display; and a controller (104) for alternately outputting a video signal and a non-image signal for applying the high voltage and driving the liquid crystal panel on a condition in accordance with the determination result of the calculating section. With this, it is possible to always display video irrespectively of fluctuation in the back transition occurrence condition.
