PURPOSE:To reduce an undesirable influence of a parallax exerted on a display characteristic of a liquid crystal display panel, and to obtain a uniform and good contrast characteristic, by providing a luminance correcting circuit for varying successively a selective voltage value of a scan driving waveform, by following a line sequential scan in one constitution screen. CONSTITUTION:In a liquid crystal display device which is an XY matrix type in which plural signal electrodes and plural scan electrodes are opposed to each other in a matrix shape, and provided with a multiplex driving circuit by a voltage averaging method, a luminance correcting circuit for varying successively a selective voltage value of a scan driving waveform by following a line sequential scan in one constitution screen is provided. Since the luminance correcting circuit for varying successively a scan voltage is added, unevenness and a fall of a contrast caused by a parallax in one screen are prevented, and even in case of a large-sized liquid crystal display panel, an image which is uniform and has a high quality can be obtained extending over the whole screen.
