Abstract:
1. A liquid crystal display apparatus which displays video by driving a liquid crystal panel in OCB mode based on a video signal, the liquid crystal display apparatus comprising: a detecting section for detecting a value of a parameter that causes fluctuations in a back transition occurrence condition; a calculating section for determining, in accordance with the detection value of the detecting section, a ratio of a 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; and a controller 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, wherein the detecting section is a temperature sensor placed in the vicinity of the liquid crystal panel, and wherein the calculating section
