Abstract
In a liquid crystal display device, scanning lines, video signal lines and pixels are formed in respective regions enclosed by the scanning lines and the video signal lines. In the liquid crystal display device, a pixel electrode and a thin-film transistor (TFT) are formed in each of the pixels, a first insulating film is formed between a common electrode formed in common for a plurality of pixels and the pixel electrode, the pixel electrode is connected to one of the video signal lines via the TFT, the TFT has a gate connected to one of the scanning lines, a constant common voltage is supplied to the common electrode, the scanning lines are sequentially scanned from a first scanning line in one frame, and a predetermined voltage is applied for a predetermined period to all the scanning lines before a scanning signal is applied to the first scanning line.
