Abstract:
A pixel circuit includes a driving transistor, a write transistor, a first switching transistor, a second switching transistor, a first storage capacitor, and a second storage capacitor. The driving transistor controls a current flowing in a light-emitting device. The write transistor controls application of a signal voltage to a gate of the driving transistor. The first switching transistor controls a gate voltage of the driving transistor upon correction operation that allows a gate-source voltage of the driving transistor to come close to a threshold voltage of the driving transistor. The second switching transistor is provided at a path between first and second terminals. The first storage capacitor is provided at a path between the gate of the driving transistor and the first terminal. The second storage capacitor is provided at a path between the gate of the driving transistor and the second terminal.
