Abstract
An electro-optical device includes a control unit that controls a display unit having a plurality of pixels. The control unit performs a differential driving operation of performing an operation of erasing a first image component which is a part of a display image in a first display state and an operation of displaying a second image component which is a part of a display image in a second display state by selectively driving the pixels having different gray scales in the first display state and the second display state when the display unit is changed from the first display state to the second display state. The operation of erasing the first image component includes an extended erasing operation of driving a first pixel group which includes the pixels constituting the first image component and the pixels being adjacent to the first image component and surrounding the first image component.
