An electro-optical device includes a plurality of pixel circuits that are
disposed to correspond to intersections of a plurality of scanning lines
and a plurality of data lines, a scanning line driving circuit that
sequentially selects the plurality of scanning lines to apply a selection
voltage to the selected scanning line, a data line driving circuit that
applies any one of an on voltage and an off voltage to the plurality of
data lines in accordance with gray-scale levels of pixel circuits
corresponding to intersections of the data lines and the selected
scanning line by the scanning line driving circuit, and a signal supply
circuit that supplies a driving signal, of which the level periodically
changes, to a signal supply line. Each of the pixel circuits has a first
transistor in which, when the on voltage is applied to a gate electrode,
a first terminal is connected to a second terminal, an electro-optical
element that is connected to the first terminal of the first transistor,
a first capacitor one end of which is connected to the second terminal of
the first transistor and simultaneously the other end of which is
connected to the signal supply line, a second capacitor one end of which
is connected to the gate electrode of the first transistor, and a second
transistor in which, when the selection voltage is applied to a gate
electrode connected to a corresponding scanning line, a first terminal
connected to a corresponding data line is connected to a second terminal
connected to one end of the second capacitor.
