ABSTRACT:
A liquid crystal device for driving a liquid crystal by an electric field generally in parallel with a substrate plane. In this liquid crystal device, voltage waveforms having phases different by a half period are separately applied to even row common electrode lines 5 and odd row common electrode lines 6, so that the charging/discharging of the inline parasitic capacitance in the liquid crystal device, created at a polarity inversion time, are reduced to decrease the power consumption. In order to reduce the bluntness of a common electrode driving signal at a thin film transistor liquid crystal display panel, moreover, a common electrode driving unit includes differential signal superposing means for generating a differential signal and superposing it upon the common electrode driving signal.
