Abstract
A pixel circuit includes a driving transistor, a write transistor, a first switching transistor, a first storage capacitor, a second and third switching transistors, 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 source end of the driving transistor. The first switching transistor controls a gate voltage of the driving transistor during 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 and third switching transistors are provided, in series, at an electrically conductive path between the source end of the driving transistor and a first voltage line.
