Abstract

A circuit for driving an electro-optical device has a plurality of pixel portions that contain an electro-optical material responsive to an electric signal. The circuit includes a driving unit that supplies an image signal corresponding to one screen to the pixel portions in each of a plurality of unit periods into which a screen display period for displaying the one screen is divided so that the pixel portions are driven a plurality of times in the screen display period. The circuit further includes a correction unit that corrects the image signal supplied in the first unit period of the plurality of unit periods in the same screen display period with correction data. The correction data is determined using the amount of change with respect to an image signal supplied in a screen display period previous to the first unit period and a response speed of the electro-optical material to the image signal.
