A driving circuit of an electro-optical device that can reduce or prevent bad influences of a transverse electric field and a crosstalk is provided. There can also be provided a driving circuit of an electro-optical device, the driving circuit generating timing signals for supplying scanning signals to a display unit in which pixels can be formed corresponding to the respective intersections between a plurality of data lines and a plurality of scanning lines arranged in a matrix shape and the switching elements provided in the pixels are turned on by the scanning signals supplied to the scanning lines, so that the image signal supplied to the data lines are applied to the pixel electrodes of the pixels through the switching elements to drive the display unit.
