Abstract: The screen of a liquid crystal display is first divided into a compensation portion, a compensation transition portion and a non-compensation portion in a sequence arranged along the scanning line. Then storage capacitor areas of the pixels in the non-compensation portion are made equal, whereas the difference between the storage capacitor area of the pixel in the compensation portion and that in the non-compensation portion is set to one constant basic compensation area. Afterward, the average of the storage capacitor areas of the pixels on each data line in the compensation transition portion progressively varies along the scanning line, where the average is greater than or equal to any of the storage capacitor areas of the pixels in the non-compensation portion. The direction of the scanning line is designated as either the direction in which scanning signals are transmitted or the direction opposite thereto.
