DRIVING CIRCUIT, DISPLAY DEVICE, AND DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a driving circuit of a light emission element capable of correcting a threshold voltage of a drive transistor by using two reference voltages without making it necessary to provide any reset power source.SOLUTION: A drive circuit includes: a light emission element for emitting light by a current flow; a drive transistor for controlling an amount of current running through the light emission element; a first switching element arranged between the light emission element and the drive transistor; a second switching element arranged nearer to a second reference voltage side than the drive transistor; a third switching element connected between gate and drain of the drive transistor; a fourth switching element connected to source of the drive transistor, and configured to be turned on in a signal writing period for supplying a signal voltage to the source of the drive transistor; and a first capacity connected between the gate of the drive transistor and a terminal on the second reference voltage side of the second switching element.
