Abstract
A driving circuit for an electro-optical device includes scan lines, data lines, and pixel portions, arranged in an image display region on a substrate. The driving circuit includes a data line driving circuit to supply a first sampling signal and a second sampling signal sequentially to the sampling switches. Each sampling switch to supply an image signal of an image signal line to each of the data lines corresponding to the first sampling signal and the second sampling signal. Each of the sampling switches includes a first transistor for sustaining the image signal according to the first sampling signal and a second transistor electrically connected in series to the first transistor for supplying the image signal sustained by the first transistor to the data lines according to the second sampling signal.
