Abstract
An electro-optical device includes a driving transistor, a first capacitor, a second capacitor, and a switching circuit. The driving transistor is connected between a power supply and an electrode of a light-emitting element. The first capacitor is connected between a gate and source of the driving transistor. The second capacitor stores a gray scale voltage. The switching circuit selectively connects the first capacitor and the second capacitor to the gate of the driving transistor. A control circuit applies the gray scale voltage to the second capacitor while the first capacitor is connected to the gate of the driving transistor by the switching circuit, and writes a source voltage of the driving transistor at the first capacitor while the second capacitor is connected to the gate of the driving transistor by the switching circuit.
