Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel with parallel provision of a plurality of common electrodes extending in a first direction on one of a pair of substrates having a liquid crystal layer interposed therebetween and a plurality of segment electrodes extending in a second direction crossing the first direction on a remaining one of the pair of substrates; a common driver for application of a scan signal to the plurality of common electrodes; and a segment driver for applying to each of the plurality of segment electrodes a pulse-width-modulated data signal voltage corresponding to display data, wherein, upon every timing of both a first timing when a signal voltage input to the segment electrode changes a smaller voltage into a larger voltage than a non-select voltage of the common electrode and a second timing when a signal voltage input to the segment electrode changes a larger voltage into a smaller voltage than the non-select voltage of the common electrode, the segment driver outputs and holds, to the segment electrode, a voltage substantially equal to the non-select voltage of the common electrode for a prescribed period of time.
