Driving circuit, liquid crystal device, electronic apparatus, and method of driving liquid crystal device

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 arranged to correspond to intersections between the plurality of scanning lines and the plurality of data lines, a second substrate disposed opposite the first substrate, and liquid crystal interposed between the first substrate and the second substrate, the common electrodes being electrically partitioned every horizontal line, the driving circuit comprising:

• a control circuit that alternately supplies a first voltage and a second voltage being higher than the first voltage to the common electrodes at predetermined interval of time and that sets the common electrodes to a floating state;
• a scanning line driving circuit that sequentially supplies a selection voltage for selecting a scanning line 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 at a predetermined interval of time when the scanning lines are selected,
• wherein the control circuit supplies the first voltage to the common electrodes and sets at least one common electrode among the common electrodes adjacent to the common electrodes supplied with the first voltage to the floating state, then the scanning line driving circuit supplies the selection voltage to the scanning lines, and the data line driving circuit supplies the positive image signal to the data lines;
• and
• wherein the control circuit supplies the second voltage to the common electrodes and sets at least one common electrode among the common electrodes adjacent to the common electrodes supplied with the second voltage to the floating state, then the scanning line driving circuit supplies the selection voltage to the scanning lines, and the data line driving circuit supplies the negative image signal to the data lines.
