Electro-optical device, driving method of electro-optical device and electronic apparatus

A first storage capacitor is provided with respect to a data line. A pixel circuit includes a first transistor supplying current according to a voltage between a gate and a source, a light emitting element emitting light corresponding to current supplied by the first transistor, and a second transistor which is configured to be turned on or off between the data line and the gate. In a first period, an initial potential is supplied to the data line by turning on the second transistor, and in a second period, a data signal of a potential corresponding to a gradation level is supplied to the first storage capacitor by turning on the second transistor. After the second period, the second transistor is turned off.
