Abstract
A pixel circuit includes a light emitting device, a driving transistor for controlling a magnitude of a driving current supplied from a first power supply to the light emitting device in response to a potential at a first node, a storage capacitor for causing a change in the potential at the first node in response to a change in a potential at a second node, a first circuit for transmitting a voltage signal in a data line to the second node in response to a signal in a first scan line being active, a second circuit for bringing the driving transistor into a diode-connecting state in response to a signal in a second scan line being active, and a third circuit.
