Abstract
A liquid crystal display device comprising, a liquid crystal panel having parallel provision of a plurality of common electrodes COM extending in a first direction on one of a pair of substrates with a liquid crystal layer interposed therebetween and parallel provision of a plurality of segment electrodes SEG extending in a second direction crossing in the first direction on the other of the pair of substrates, a common driver for applying a scan signal(s) to the plurality of common electrodes COM, and a segment driver for applying to each of the plurality of segment electrodes SEG a pulse-width-modulated data signal voltage corresponding to display data, wherein the segment driver is operable upon switching of the pulse-width-modulated data signal voltage input to the segment electrode SEG to temporarily output to the segment electrode a voltage which is substantially equal to a non-select voltage of the common electrodes COM.
