Abstract
In a liquid crystal display device, an auxiliary capacitance wiring driver changes a potential of an auxiliary capacitance wiring so that a dielectric torque of liquid crystal molecules of a pixel (PXj) to which a minimum voltage corresponding to a backlight is written becomes larger while the backlight is turned off, and a scanning signal line driver drives a scanning signal line so that image data is written to the pixel in a state in which the potential of the auxiliary capacitance wiring is changed so that the dielectric torque of the liquid crystal molecules of the pixel becomes larger.
