A unit circuit includes a capacitive element having a first electrode, a second electrode, and a dielectric layer interposed between the first electrode and the second electrode, a transistor having a gate electrode connected to the first electrode, a first terminal supplied with one of a low potential and a high potential, a second terminal connected to a driven element, a first switching element controlling electrical connection between the gate electrode of the transistor and the second terminal, and a second switching element connected to the second electrode. A potential of the first electrode is set to a predetermined potential higher than a first potential, and the potential of the first electrode is set to the first potential in a state that the first electrode is electrically isolated from the predetermined potential by turning off the first switching element.
