ABSTRACT:
A scanning signal from a scanning electrode drive circuit and a data signal from a signal electrode drive circuit are applied to a liquid crystal panel to perform image display in the liquid crystal panel. Here, as well as power supply to the scanning electrode drive circuit and the signal electrode drive circuit being from separate power supply circuits, a voltage for producing a data signal in the liquid crystal drive voltage power supply circuit is generated with a central voltage of a liquid crystal drive voltage power supply circuit, which is for generating a voltage for producing the scanning signal, as a reference voltage. Because power is supplied separately to the scanning electrode drive circuit and the signal electrode drive circuit, the breakdown voltage of the signal electrode drive circuit is alleviated and thus power consumption is reduced, and further, flickering does not occur in the display, etc., even if there are fluctuations in the power supply voltage.
