ABSTRACT:
A driving circuit includes a plurality of scanning lines, a plurality of data lines, a plurality of capacitor lines, pixels, a scanning line driving circuit, a capacitor line driving circuit, a first capacitive signal output circuit, and a data line driving circuit. Each of the pixels includes a pixel switching element, a pixel capacitor, and a storage capacitor. The capacitor line driving circuit supplies a first capacitive signal to the capacitor line when the one scanning line is selected, and changes a voltage value of the first capacitive signal when a scanning line, located a predetermined number of scanning lines away from the one scanning line, is selected. The first capacitive signal output circuit adjusts and outputs a voltage of the first capacitive signal when the one scanning line is selected. The data line driving circuit supplies the pixels with data signals of voltages corresponding to gray scale levels.
