Abstract
The vertical scan period of the input video signal is divided into at least two sub-frames. In each of the sub-frames, a display signal voltage is written into each pixel. Two vertical scan periods in which the input video signals are continuous contain a sequence of two continuous sub-frames where a display signal voltage is written with the same polarity and a sub-frame where the polarity of the display signal voltage is inversed. The auxiliary capacity opposing voltage includes, in each of the sub-frames, a first waveform vibrating with a first cycle of the horizontal scan period multiplied by an integer not smaller than 2 and a second waveform in which an effective value of the auxiliary capacity opposing voltage is set to a predetermined constant value for each vertical scan period of a predetermined number of continuous input video signals.
