Liquid crystal display device, method for driving liquid crystal display device, and electronic apparatus

A method for driving a liquid crystal display device comprising:

• a pixel array unit in which pixels including a liquid crystal cell are arranged in a matrix;
• a plurality of scan lines that selects the pixels row by row, the plurality of scan lines extending along a row direction;
• common wiring that supplies a voltage to a counter electrode in the liquid crystal cell;
• and
• a plurality of data lines that supplies a voltage to a pixel electrode in the liquid crystal cell, the plurality of data lines extending along a column direction,
• wherein each of the pixels includes a pixel transistor connecting a data line in the plurality of data lines and the pixel electrode, and
• wherein a conductive state/a non-conductive state of the pixel transistor is controlled by a scan signal voltage applied to a scan line of the plurality of scan lines,
• the method comprises:
• supplying a signal voltage whose polarity is inverted in regular cycles to the common wiring;
• and
• supplying a scan signal voltage supplied to the scan line of the plurality of scan lines when no pixel is selected such that the scan signal voltage varies, between a positive voltage value and a negative voltage value, with the positive voltage value being at least twice that of the negative voltage value, in accordance with a position at which the pixels are selected row by row in the pixel array unit.
