Abstract
An electro-optical device includes pixels provided at intersections of a plurality of scanning lines and a plurality of data lines, a scanning line driving circuit for applying a selected voltage to the respective scanning lines, and a data line driving circuit for applying a turning-on voltage or a turning-off voltage to the respective data lines. The data line driving circuit alternately changes between leading-edge driving including applying the turning-on voltage to a data line corresponding to one of the pixels in a period from the starting point of a period when the selected voltage is applied to the scanning line corresponding to the pixel to the point of time after the lapse of time corresponding to the gray scale of the corresponding pixel and trailing-edge driving including applying the turning-on voltage to the data line corresponding to the pixel in a period from a point of time preceding the final point of the period when the selected voltage is applied to the scanning line corresponding to the pixel by the length of time corresponding to the gray scale of the corresponding pixel to the final point.
