PROBLEM TO BE SOLVED: To display an image of high quality by an electrooptical device using liquid crystal etc., by reducing variation in pixel voltage due to coupling noise generated when an image signal is inverted in polarity. SOLUTION: The electrooptical device has a plurality of pixel electrodes 9a, a plurality of scanning lines 11a, a plurality of data lines 6a, an image signal line 6 supplied with the image signal VID whose potential is inverted in polarity about a common potential LCC in every horizontal scanning period, and a sampling circuit 7 which supplies the image signal VID to the plurality of data lines 6a according to a sampling signal Si. Further, the electrooptical device is equipped with a data line driving circuit 101 which outputs the sampling signal Si, a plurality of TFTs 30 which are electrically connected to the plurality of pixel electrodes 9a, and a scanning line driving circuit 104 which supplies a scanning signal Gi switching a TFT 30 from an on state to an off state to the plurality of scanning lines 11a in timing shifting from the timing wherein the image signal VID is inverted in polarity by a predetermined periodΔT2.
