Abstract:
An electro-optical device includes a pixel circuit, and a driving circuit. The pixel circuit includes a driving transistor, a first capacitive element, an electro-optical element, and a switch. The driving circuit controls the switch to be turned off, varies a potential such that the driving transistor is turned on, during a first period, sets a potential at a control terminal to a compensation initial value by controlling the switch to be turned on, during a second period, supplies a grayscale potential corresponding to a designated grayscale, varies a driving potential such that the driving transistor is turned on, during a third period, and varies a voltage between the control terminal and a first terminal with the passage of time, during a fourth period.
