To solve the problem wherein abnormal currents are produced between the different gradation voltages when recovering charges, while spoiling its power saving feature.

A gradation signal output circuit outputs the digital gradation signals in two or more complimentary signals. A gradation voltage output circuit outputs analog gradation voltages. A gradation signal wiring receives the output of the gradation signal output circuit. A gradation voltage wiring receives the output of the gradation voltage output circuit. A digital-analog converter circuit selectively outputs the analog gradation voltage, given by the gradation voltage wiring corresponding to the digital gradation signals given by the gradation signal wiring. A first switch 42 cuts off the gradation signal output circuit from the gradation signal wiring or cuts off the gradation signal wiring. A second switch 43 cuts off the gradation voltage output circuit from the gradation voltage wiring or cuts off the gradation voltage wiring; or a third switch 41 connects the pair of this gradation signal wiring, transmitting the pair of the complimentary signals.
