An electro-optical device includes a first pixel provided corresponding to intersection of a first data line and a scanning line, a second pixel provided corresponding to intersection of a second data line and the scanning line, a data signal circuit configured to supply a first data signal to the first pixel via the first data line in a first period and supply a second data signal to the second pixel via the second data line in a second period that is started after completion of the first period, and a pre-charge circuit configured to supply a second pre-charge signal to the second data line in the first period after supplying a first pre-charge signal to the second data line in the first period.
