ABSTRACT:
A liquid crystal display apparatus comprises a liquid crystal display panel, a temperature sensor which detects temperature of the liquid crystal display panel, and a controller which controls a voltage applied to the liquid crystal display panel. The controller sets a black-insertion ratio to 0% and changes the voltage applied in white-display mode to a voltage equal to or higher than the critical voltage, or sets a black-insertion ratio to a finite value and changes the voltage applied in the white-display mode to a voltage lower than the critical voltage, in accordance with the temperature detected by the temperature sensor.
