摘要： Disclosed is a liquid crystal display capable of ensuring brightness necessary for achieving satisfactory display by increasing ratio of light-emitting time to one frame period. A liquid crystal display is adapted to have a period (non-video signal write period) required for writing non-video signals different from video signals onto all the pixels before a video signal write period. In the non-video signal write period, the non-video signals are written onto the respective pixels, thereby starting response of the liquid crystal before the start of the video signal write period. In the non-video signal write period, a backlight is turned off, and thereby image degradation is prevented even when the non-video signals are written onto the respective pixels.

摘要： A liquid crystal display panel of the invention is such that, in a pixel region defined by a region of the array substrate surrounded by a pair of image signal lines and a pair of scanning signal lines, of a line-shaped pixel electrode and a common electrode, the electrode that is disposed adjacent to and parallel to a signal line is made of an opaque conductor and at least one of the other electrodes is made of a transparent conductor. Adverse effects of the electric field formed between a signal line and an adjacent electrode thereto are suppressed and a sufficient aperture ratio is ensured by using a transparent conductor for the electrode contributing good display.
