Abstract:
A drive circuit for a light emitting element which can correct a threshold voltage of a drive transistor between two reference voltages without a reset power supply. The drive circuit includes a light emitting element, a drive transistor for controlling an amount of current, a first switching element that is arranged between the light emitting element and the drive transistor, a second switching element that is arranged between the drive transistor and the second reference voltage, a third switching element that is arranged between a gate, and one of a source and a drain of the drive transistor, a fourth switching element that is connected to the other of the source and the drain of the drive transistor, and controls input of signal voltage, and a first capacitor connected to the gate of the drive transistor.
