A liquid crystal display device with a charge sharing function is suitable for reducing the power consumption below a predetermined limit. In the liquid crystal display device, a pair of pixels adjacent along the data line is charged with pixel data voltages of polarity opposite to that of another pair of pixels adjacent to the pair of the pixels. A charge sharing unit selectively allows the data lines to share charges at intervals between periods in which the pixel data voltages are supplied to the pair of the pixels adjacent along the data line.
