Abstract
A liquid crystal display device includes: a liquid crystal display unit including pixels and displaying an image based on an input image signal; a drive unit that applies a voltage based on the input image signal to the pixels while inverting a polarity of the voltage for each of frames; a luminance determination unit that determines whether a detected average luminance has changed, between the frames, by an amount equal to or more than a reference luminance; and a signal generation unit that generates a phase inversion enabling signal for inverting a phase of the polarity of the voltage applied to the pixels, in a case where the luminance determination unit determines that the average luminance has changed by the above amount, wherein the drive unit inverts the phase of the polarity of the voltage applied to the pixels when the phase inversion enabling signal is generated.
