ABSTRACT:
A power supply circuit including: a high-potential-side voltage generation circuit which generates a high-potential-side voltage to be supplied to the common electrode; a low-potential-side voltage generation circuit which generates a low-potential-side voltage to be supplied to the common electrode; and a switch circuit which alternately supplies the high-potential-side voltage and the low-potential-side voltage to the common electrode as a common electrode voltage. The power supply circuit performs supply capability control of the common electrode voltage which changes at least one of current drive capability of the high-potential-side voltage generation circuit, an output voltage level of the high-potential-side voltage generation circuit, current drive capability of the low-potential-side voltage generation circuit, and an output voltage level of the low-potential-side voltage generation circuit according to line data including grayscale data for the number of dots of one scan line, each dot corresponding to voltage applied to the pixel electrode.
