Abstract
The invention provides an electro-optical device that stabilizes display quality by performing correction processing corresponding to a plurality of disturbance factors. Specifically, a grayscale characteristic generating unit can generate conversion data having grayscale characteristics obtained by changing the grayscale characteristics of display data that defines the grayscales of pixels with reference to a conversion table whose description contents include correction factors. A data line driving circuit can drive the pixels after correcting the grayscale characteristics of the conversion data by the correction factors using other processing different from the that performed by the grayscale characteristic generating unit.
