Abstract: The liquid crystal display device includes a resistive string that divides each of voltage ranges between reference voltages to generate multi-level grayscale voltages to be applied to the liquid crystal layer. The resistances between the terminals of the resistive string to which the reference voltages are applied are set to magnitudes almost proportional to voltage differences between the reference voltages. This makes it possible to provide a liquid crystal display device with low power consumption and high picture quality.

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.
