  • Patent number: 11562707
    Abstract: The display control circuit includes a drive signal generation circuit that generates a gate drive signal, a scanning line drive circuit that supplies the gate drive signal to the scanning line, and a first wire through which the gate drive signal from the drive signal generation circuit is supplied to the scanning line drive circuit. The drive signal generation circuit includes a first potential supply circuit that supplies, to the first wire, a first potential equal to or lower than an off-potential of the pixel transistor, a second potential supply circuit that supplies, to the first wire, a second potential lower than the first potential, a third potential supply circuit that supplies, to the first wire, a third potential higher than the first potential, and a fourth potential supply circuit that supplies, to the first wire, a fourth potential equal to or higher than an on-potential of the pixel transistor.
