An electro-optical device includes a plurality of pixel circuits each including a light-emitting element and a driving transistor for driving the light-emitting element; data lines that are connected to the plurality of pixel circuits and that supply data signals representing light-emitting gray-scale levels to the pixel circuits; and a data line driving circuit that supplies the data signals to the pixel circuits through the data lines. In addition, the data line driving circuit applies to each pixel circuit in a predetermined sequence a forward frame period supplying a data signal having a forward bias voltage for making the light-emitting element emit light and a backward frame period supplying a data signal having a backward bias voltage for making the light-emitting element not emit light, and drives each of the pixel circuits.
