An electro-optical device includes a plurality of data lines, a plurality of scanning lines, a plurality of unit circuits that are provided in correspondence with intersections of the data lines and the scanning lines. Each of the data lines is supplied with a data voltage in accordance with a gray-scale level. Each of the scanning lines is supplied with a scanning signal that specifies a writing period during which the data voltage is being written into the corresponding unit circuits. Each of the plurality of unit circuits includes a driving transistor, an electro-optical element, a capacitive element, a power feed liner a first switching element and a second switching element. The driving transistor generates a driving current in accordance with an electric potential of a gate thereof. The electro-optical element generates light with a gray-scale level in accordance with the driving current that is generated by the driving transistor. The capacitive element has a first electrode and a second electrode that is connected to the gate of the driving transistor. The power feed line is supplied with a constant electric potential and is, during an initialization period that is different from the writing period, electrically connected to the second electrode. The first switching element conducts the gate of the transistor with the drain thereof at least during the initialization period. The second switching element switches between conduction and non-conduction between the data line and the first electrode on the basis of the scanning signal. The power feed line is arranged in a direction that intersects with the scanning lines.
