Abstract
A liquid crystal display device includes: a pixel array unit in which pixels including a liquid crystal cell are arranged in a matrix; scan lines; common wiring; and data lines, in which each of the pixels includes a pixel transistor connecting the data line and the pixel electrode, a conductive state/a non-conductive state of the pixel transistor is controlled by a scan signal voltage applied to the scan line, a signal voltage whose polarity is inverted in regular cycles is supplied to the common wiring, and at least one of a pre-charge voltage supplied to the data line prior to writing of a video signal voltage or a scan signal voltage supplied to the scan line when no pixel is selected is supplied so as to vary in accordance with the position at which the pixels are selected row by row in the pixel array unit.
