Abstract
An optical modulation device comprises a first substrate having thereon a first conductor film, a second substrate having thereon a second conductor film disposed opposite to the first conductor film, and an optical modulation material disposed between the first and second substrates. The optical modulation device is driven by forming a potential gradient along the extension of the first conductor film or both the first and second conductor films, and applying an information signal to the first or second conductor film.
