Abstract
In a method of driving a liquid crystal display (“LCD”) apparatus, a common voltage is applied to a common electrode above a liquid crystal layer and pixel voltages are applied to pixel electrodes under the liquid crystal layer to form an electrical field with the common electrode to control movements of liquid crystal molecules of the liquid crystal layer. Each of the pixel electrodes has slits. Then, a supplementary voltage is applied to a supplementary electrode between the slits of each pixel electrode to compensate the electric field formed by the pixel electrodes and the common electrode.
