Abstract
A pixel circuit driving method is a method for driving a pixel circuit that includes a drive transistor that supplies a current corresponding to a signal voltage supplied via a signal line, a write transistor connected between the signal line and a gate electrode of the drive transistor, and an organic EL element that emits light in accordance with the current. The pixel circuit driving method includes supplying a reference potential to the gate electrode of the drive transistor before a threshold correction preparation operation of making a gate-source voltage of the drive transistor higher than a threshold voltage of the drive transistor.
