An electro-optical device may include a plurality of data lines, a plurality of selection lines, a plurality of unit circuits, a selection circuit, and a control circuit. Each of the plurality of unit circuits is connected to a corresponding one of the plurality of data lines and a corresponding one of the plurality of selection lines. The plurality of unit circuits form a unit circuit group for each of the selection lines. The selection circuit supplies a selection signal to one of the plurality of selection lines so that data signals are written from the plurality of data lines to the corresponding unit circuit group during a selection period when the corresponding unit circuit group is selected. The control circuit supplies a common control signal to the unit circuits included in a group consisting of two or more of the unit circuit groups. The control circuit brings the control signal into a predetermined state during a period that is different from the selection period when any one of the two or more unit circuit groups is selected. Here, each of the plurality of unit circuits includes an electro-optical element, a first switching element, a driving transistor. The first switching element writes the data signal from one of the plurality of data lines to the corresponding unit circuit in accordance with the selection signal. The gate of the driving transistor is supplied with a voltage corresponding to the data signal. The driving transistor supplies a driving current to the electro-optical element.
