Abstract
A voltage supply circuit which switches a first voltage supplied to an electrode to a second voltage and supplies the second voltage to the electrode including: a first voltage boost circuit including a switching element for generating a boosted voltage boosted by charge-pump operation; and a charge supply circuit for supplying a charge to the electrode. When the first voltage is switched to the second voltage, the charge supply circuit supplies a charge to the electrode so as to maintain the voltage of the electrode at the second voltage after the boosted voltage has been supplied to the electrode.
