Electro-optical device, method of driving electro-optical device, electronic apparatus, and projector

A method of driving an electro-optical device including a first substrate and a second substrate facing each other with an electro-optical medium sandwiched therebetween, a pixel region having a plurality of pixels, and an ion trap section having an electrode formed in a region outside of the pixel region, the method comprising:

• at a time of setting a trapping voltage applied to the electrode of the ion trap section on the basis of a calculated voltage value that is calculated from a driving voltage applied to the electro-optical medium in one or a plurality of the pixels serving as a reference,
• setting the trapping voltage relatively high when the calculated voltage value belongs to a relatively high voltage range;
• and
• setting the trapping voltage relatively low when the calculated voltage value belongs to a relatively low voltage range,
• wherein the plurality of the pixels serving as the reference are a plurality of the pixels located on an outermost periphery of the pixel region.
