ABSTRACT:
A liquid crystal display device according to the present invention includes: a liquid crystal panel11; a source driver12for controlling the gray-scale level by applying a voltage to the liquid crystal panel11; a DC-DC power supply13for driving the source driver12by supplying current to the source driver12; a controller14for supplying a signal for controlling the gray-scale level to the source driver12; and a variation calculator15for calculating the amount of change in the signal from the controller14. In the DC-DC power supply13, current to be supplied to the source driver12changes in accordance with the amount of change in the signal calculated by the variation calculator15.
