Abstract
A method of driving a plurality of pixel circuits. The pixel circuits are disposed corresponding to intersections between a plurality of scanning lines and a plurality of signal lines. Each of the pixel circuits includes: a light emitting element; a driving transistor; a holding capacitor; and a selection switch electrically interconnecting the signal line and the gate of the driving transistor at the time of the selection of the scanning line. The method includes: supplying a gradation potential to each signal line during a first period, selecting the scanning line during a second period, and supplying the gradation potential to the gate of the driving transistor; controlling the driving transistor of each of the pixel circuits to be in an ON state, supplying a reference potential to the gate of the corresponding driving transistor, and executing a first compensation operation and supplying driving current to the light emitting element.
