Abstract:
An electro-optical device comprising:a plurality of data line pairs extending in a first direction, each of the data line pairs including a first data line to which a data signal of a first polarity is supplied and a second data line to which a data signal of a second polarity is supplied; a plurality of scanning lines extending in a second direction that intersects the first direction; a plurality of pixels arranged at intersections of the data lines pairs and the scanning lines; a scanning line driving circuit which supplies each of the scanning lines with a scanning signal for selecting one of the scanning lines in a selection period; and a data line driving circuit which includes a data line switching circuit and supplies the first and second data lines of the data line pairs with the data signals of the first and second polarities, respectively, wherein the data line switching circuit selects one of the first and second data lines of each of the data line pairs alternately along the second direction in a t-th selection period (t is a natural number) of a k-th (k is a natural number) frame period, and then in the (t+1)-th selection period, selects the other of the first and second data lines of each of the data line pairs which has not been selected in the t-th selection period.
