A system for driving a nematic liquid crystal in a liquid crystal display device which includes a nematic liquid crystal, a plurality of common electrodes and a plurality of segment electrodes confining the nematic liquid crystal therebetween, and a pair of polarizing plates sandwiching the common electrodes and the segment electrodes confining the nematic liquid crystal, comprises means for applying a sequence of selection pulses to the common electrodes; means responsive to the selection pulses to apply to the segment electrodes a voltage corresponding to image data to be displayed; and means for applying to the segment electrodes a voltage different from the voltage corresponding to the image data in intervals where the selection pulses are not applied. The voltage applied to the segment electrodes is controlled such that the mean value of the voltage be a predetermined constant value.
