Abstract
Official abstract text for this publication.
An electro-optical device of the invention includes 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. A trapping voltage applied to the electrode of the ion trap section varies in accordance with 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. The trapping voltage is set relatively high when the calculated voltage value belongs to a relatively high voltage range, and the trapping voltage is set relatively low when the calculated voltage value belongs to a relatively low voltage range.
