Claim:
1. A lateral electric field type liquid crystal display comprising: an array substrate that includes: a plurality of signal lines and a plurality of scan lines arranged in a matrix to form pixel areas; switching elements formed corresponding to the intersections of the signal lines and the scan lines; pixel electrodes connected to the switching elements, and a common electrode formed to face the pixel electrodes with interposing an insulating film; a counter substrate that faces the array substrate; and a liquid crystal material that is interposed between the array substrate and the counter substrate, wherein the liquid crystal material responds to an electric field parallel to a surface of the array substrate, and wherein in a vertical blanking period, which is a blanking period of a vertical period for sequentially applying scan signals to all of the scan lines, a common electrode potential is changed so that a potential difference between the common electrode potential and the pixel electrode potential becomes smaller than that before the vertical blanking period.
