ABSTRACT:
The liquid crystal display apparatus of the present invention includes: a liquid crystal panel having a liquid crystal layer and an electrode for applying a voltage to the liquid crystal layer; and a drive circuit for supplying a drive voltage to the liquid crystal panel. The drive circuit supplies a drive voltage obtained by giving an overshoot to a gray-scale voltage corresponding to an input image signal in the current vertical period, the drive voltage being determined in advance according to a combination of an input image signal in the immediately-preceding vertical period processed based on a predicted value of the transmittance of the liquid crystal panel in the immediately-preceding vertical period and the input image signal in the current vertical period.
