1. A liquid crystal device comprising:
- a plurality of scanning lines;
a plurality of data lines that intersect with the scanning lines;
a plurality of pixel electrodes that are provided at positions corresponding to intersections of the plurality of scanning lines and the plurality of data lines;
a capacitor electrode that is provided opposite each of the pixel electrodes and that forms a capacitor with each of the pixel electrodes or with an electrode layer connected to each of the pixel electrodes;
a control circuit that alternately supplies the capacitor electrode with a first voltage or a second voltage that is higher in electric potential than the first voltage;
a scanning line driving circuit that sequentially supplies the plurality of scanning lines with a scanning line selection voltage that selects the scanning line; and
a data line driving circuit that, when the scanning line is selected, alternately supplies the plurality of data lines with a positive polarity image signal that is higher in electric potential than the first voltage or a negative polarity image signal that is lower in electric potential than the second voltage, whereinthe control circuit includes a selection circuit and a selection signal output circuit, whereinthe selection circuit alternately selects and outputs the first voltage or the second voltage to the capacitor electrode, whereinthe selection signal output circuit outputs a selection signal to the selection circuit, and whereinthe first voltage is higher in electric potential than a low electric potential of the selection signal, and the second voltage is lower in electric potential than a high electric potential of the selection signal.
