An electro-optical device includes a plurality of scanning lines that extends in a row direction, a plurality of data lines that extends in a column direction, a plurality of pixels which are provided at intersections of the scanning lines and the data lines and whose gray-scale levels are designated by data signals supplied through the data lines, a common electrode that is provided so as to be opposite to pixel electrodes, a shift register that outputs sampling signals to sequentially select a plurality of blocks each composed of a plurality of the data lines, in a period where the scanning lines are selected, a sampling circuit that samples the data signals to the plurality of data lines belonging to the block selected by the sampling signal, respectively, a data signal supply circuit that changes the potential of the data signal into a higher level and a lower level than a predetermined potential in every predetermined period and then alternately outputs the potentials, and a correction circuit that superimposes, on the data signals, correction signals for correcting potential errors that are generated in the data lines belonging to each of the blocks, corresponding to the potentials of the data lines.
