ABSTRACT:
A plurality of ON signal voltages are applied to a thin film transistor (TFT) within one field period, thereby transmitting an image signal voltage to a pixel electrode, two types of modulation signals are alternately supplied to a first wiring (17) at every field during an OFF period of the thin film transistor so that the potential of the pixel electrode is changed, and the change of the potential is superimposed on and/or offset by an image signal voltage so as to apply a resultant voltage to a display material to be driven. Before the termination of a first ON period of the plurality of ON signal voltages applied to the thin film transistor, a part of the potential of the modulation signal is varied.
