摘要： The present invention realizes a liquid crystal display device and an image display device which prevent the generation of flickering when power is supplied again after the supplying of power is stopped. The liquid crystal display device includes first and second substrates which are arranged to face each other in an opposed manner, a liquid crystal layer which is inserted between the first and second substrates, active elements, scanning signal lines for operating the active elements and pixel electrodes to which video signals are supplied upon operation of the active elements which are all mounted on one substrate, an orientation film which is inserted between the pixel electrodes and the liquid crystal layer, and reference electrodes which are mounted on either one or the other substrate, and the liquid crystal display device performing a display by generating the potential difference between the pixel electrodes and the reference electrode. In such a liquid crystal display device, the charge of the pixel electrodes is rapidly released when the supplying of power to the liquid crystal display device from the outside is stopped.
