UNIT CIRCUIT, METHOD OF CONTROLLING UNIT CIRCUIT, ELECTRONIC DEVICE, AND ELECTRONIC APPARATUS

A unit circuit includes: a capacitive element having a first electrode, a second electrode, and a dielectric layer interposed between the first and second electrodes; a transistor having a gate electrode connected to the first electrode; a first switching element that controls an electrical connection between the first electrode and a predetermined electric potential; and a second switching element connected to the second electrode. The electric potential of the first electrode is set to the predetermined electric potential by turning on the first switching element, and then, under a state in which the first electrode is electrically disconnected from the predetermined electric potential by turning off the first switching element, the electric potential of the first electrode is set to a first electric potential by a first operation signal supplied to the second electrode through the second switching element which is set to an ON state. After a first period during which the electric potential of the first electrode is set to the first electric potential is completed, a second period during which the electric potential of the first electrode is set to the predetermined electric potential by turning on the first switching element and a second operation signal is supplied to the second electrode through the second switching element which is set to the ON state is provided. After the second period is completed, under a state in which the first electrode is electrically disconnected from the predetermined electric potential by turning off the first switching element, the electric potential of the first electrode is set to a second electric potential by a third operation signal supplied to the second electrode through the second switching element which is set to the ON state. The first and second electric potentials have opposite polarities to each other when the predetermined electric potential is set to a reference potential.
