ABSTRACT:
A driving circuit for driving a liquid crystal device that has, a first substrate including a plurality of scanning lines, a plurality of data lines, and a plurality of pixel electrodes and a plurality of common electrodes, a second substrate disposed opposite the first substrate, and liquid crystal, the common electrodes being partitioned every horizontal line, the driving circuit includes: a control circuit that alternately supplies a first voltage and a second voltage being higher than the first voltage to the common electrodes and that sets the common electrodes to a floating state; a scanning line driving circuit that sequentially supplies a selection voltage to the plurality of scanning lines; and a data line driving circuit that alternately supplies a positive image signal having a potential higher than the first voltage and a negative image signal having a potential lower than the second voltage to the plurality of data lines.
