Claim:
1. A method of driving a display device comprising: a plurality of scanning signal lines and a plurality of data signal lines intersecting the plurality of scanning signal lines; a plurality of pixel formation portions disposed in a matrix form at respective intersections of the plurality of scanning signal lines and the plurality of data signal lines; a scanning signal line drive circuit that selects in turn the plurality of scanning signal lines; and a data signal line drive circuit that applies signal voltages of image signals to the plurality of data signal lines to write the signal voltages to pixel formation portions connected to a selected scanning signal line, wherein each of the pixel formation portions includes: a pixel electrode to which a corresponding one of the signal voltages is applied; a counter electrode to which a counter voltage is applied, the counter electrode being provided so as to face the pixel electrode; a switching element that provides the signal voltage to the pixel electrode connected to the selected scanning signal line; and a holding capacitance that holds a drive voltage determined by the signal voltage applied to the pixel electrode and the counter voltage applied to the counter electrode, the signal voltage includes a positive signal voltage and a negative signal voltage, the method comprising the steps of:
