Abstract:
1. A driving circuit of an electro-optical device for driving pixels provided at intersections of a plurality of scanning lines and a plurality of data lines, the driving circuit comprising: a scanning line driving circuit sequentially selecting the plurality of scanning lines and applying a selected voltage to the selected scanning lines; and a data line driving circuit performing, on the plurality of data lines, one of: applying the turning-off voltage in the remainder of the greater period, wherein the data line driving circuit drives the respective data lines that belong to a first group among the plurality of data lines by the one of the leading-edge driving and the trailing-edge driving in the period when the selected voltage is applied to the respective scanning lines, drives the respective data lines that belong to a second group different from the first group by a different driving mode than the one of the leading-edge driving and the trailing-edge driving used for the first group, and alternately changes the driving modes between the leading-edge driving and the trailing-edge driving for the respective data lines when the selected voltage is applied to the scanning line corresponding to one pixel.
