Abstract
A method of controlling an electro-optical device includes controlling a driving section such that, when an image is rewritten from a first image displayed in a first gradation to a second image including a background image portion to be displayed in the first gradation and a main image portion to be displayed in a second gradation, the same potential as a counter electrode is supplied to a pixel in the background image portion, and a potential corresponding to the second gradation is supplied to a pixel in the main image portion. The driving section is controlled such that at least one of the magnitude and application time of a voltage applied between the pixel electrode and the counter electrode is smaller in a pixel corresponding to an edge portion in the main image portion than in a pixel corresponding to a non-edge portion in the main image portion.
