Abstract:
1. A method of driving an electro-optical device including a plurality of pixels, one of the plurality of pixels having a first electrode, a second electrode opposed to the first electrode, and an electro-optical material layer disposed between the first electrode and the second electrode, a state of the electro-optical material layer changing when an electric field is applied between the first electrode and the second electrode, the method comprising: when an image displayed by the plurality of pixels is rewritten, selecting a first display state of the one pixel by applying a first voltage to the first electrode and applying a second voltage to the second electrode, or selecting a second display state of the one pixel by applying the first voltage to the first electrode and applying a third voltage which has a reverse polarity to that of the second voltage with respect to the first voltage to the second electrode; and when a part of the image is rewritten, selecting any of the first display state and the second display state of the one pixel by applying a fourth voltage which is different from the first voltage to the first electrode and applying a fifth voltage which has a different polarity from that of the fourth voltage with respect to the first voltage to the second electrode.
