Claim Text:
1. A display device comprising a scanner circuit and a plurality of pixel circuits; at least one of the pixel circuits including: wherein the drive transistor is configured to control a driving current provided for the light emitting element during a light emission period, the driving current being provided through a current path between a power supply line and a ground line according to an image signal provided via a signal line; the correction circuit includes a first transistor and a second transistor, and is configured to provide, in a predetermined period before the light emission period, a current through the drive transistor and the first transistor to the storing capacitance, the first transistor is connected to the drive transistor, and the second transistor is put in a cut-off state during the predetermined period and is put in a conductive state in the light emission period, such that the correction circuit sets a potential of a gate node relative to a current node of the drive transistor during the light emission period to a value depending on both of a characteristic data of the drive transistor and the image signal.
