Electro-optical device and electronic device

An electro-optical device that alternately displays right-eye images during a first display period and left-eye images during a second display period, comprising:

• a plurality of pixels arranged corresponding to interconnections between a plurality of scan lines and a plurality of signal lines;
• and
• a drive circuit sequentially selecting one or more scan lines of the plurality of scan lines during a preparation period of each of the first and second display periods and supplying a preparation potential to one or more pixels of the plurality of pixels corresponding to the one or more scan lines in a selection state, and sequentially selecting one or more scan lines of the plurality of scan lines during a drive period of each of the first and second display periods, the drive period starting before selecting a last scan line of the plurality of scan lines during the preparation period of each of the first and second display periods, and supplying grayscale potential that is in response to an assigned grayscale corresponding to each of one or more pixels of the plurality of pixels corresponding to the one or more scan lines in the selection state.
