Abstract: In a liquid crystal display, an image-defining data voltage is simultaneously applied to a main pixel electrode (MPE) and an electrically isolatable sub pixel electrode (SPE) to thereby respectively define a main pixel voltage and a sub pixel voltage. The MPE defines one plate of a first capacitor whose other plate receives a first common voltage whose voltage level can be varied after the image-defining data voltage is applied. Thus the main pixel voltage is shifted up or shifted down according to the voltage variation of the first common voltage. The SPE defines one plate of a second capacitor whose other plate receives a second common voltage. By causing the main pixel voltage to be of greater absolute amplitude than the sub pixel voltage, a side visibility of the liquid crystal display can be enhanced.
