ABSTRACT:
A liquid crystal display device is provided which is capable of reducing flicker over all areas of a liquid crystal panel. A common voltage having a predetermined level is fed to the liquid crystal panel and a reference voltage is fed from a digital-analog converter to a liquid crystal driving circuit and an image corresponding to a pixel data signal is displayed. The pixel data signal is reversed relative to a reference voltage for every one horizontal period. The reference voltage having been adjusted so as to be higher in side portions rather than central portions in the liquid crystal panel is applied to the liquid crystal driving circuit. As a result, even if a common voltage is not made uniform through entire portions of a common electrode, adjustment can be achieved so that flicker is minimized over all areas in the liquid crystal panel.
