Abstract

See full text

An electro-optical device includes pixels that are provided to correspond to intersections of a plurality of rows of scanning lines and a plurality of columns of first data lines, each pixel having an pixel electrode, a common electrode that faces the pixel electrode, a first transistor that is turned on when a corresponding scanning line is selected to supply a data signal from a first data line to the pixel electrode, and a second transistor that is turned on when another scanning line than the corresponding scanning line is selected prior to the corresponding scanning line to supply a data signal from the first data line or a data line different from the first data line to the pixel electrode, a scanning line driving circuit that selects the plurality of rows of scanning lines according to a predetermined sequence, when one scanning line is selected, applies a first voltage so as to turn on the first or second transistor, when the selection ends, applies a second voltage so as to turn off the first and second transistors, and, when a scanning line next to the scanning line is selected, applies a third voltage between the first voltage and the second voltage so as to turn off the first and second transistors, and a data line driving circuit that supplies a data signal according to a grayscale level of a pixel of the selected scanning line through the first data line.
