  • Patent number: 12027532
    Abstract: An object is to provide a semiconductor device which can suppress characteristic deterioration in each transistor without destabilizing operation. In a non-selection period, a transistor is turned on at regular intervals, so that a power supply potential is supplied to an output terminal of a shift register circuit. A power supply potential is supplied to the output terminal of the shift register circuit through the transistor. Since the transistor is not always on in a non-selection period, a shift of the threshold voltage of the transistor is suppressed. In addition, a power supply potential is supplied to the output terminal of the shift register circuit through the transistor at regular intervals. Therefore, the shift register circuit can suppress noise which is generated in the output terminal.
