Abstract:
1. An electro-optical device comprising: a display unit in which an electro-optical material layer is interposed between a pair of substrates and a plurality of pixels are arranged; and a control unit that drives and controls the display unit, wherein 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, and 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, wherein the extended erasing operation includes driving the first pixel group with a different gray scale from a first gray scale which the pixels of the first pixel group were driven during the first display state and wherein the different gray scale is also different from a second gray scale with which the pixels of the first pixel group will be driven in the second display state.
