Abstract
Official abstract text for this publication.
A suspended particle device includes a first substrate; a second substrate; a first electrode that can be controlled for a potential; a second electrode that can be controlled for a potential different from that of the first electrode; an electrified body; and a liquid suspension containing charged light control particles and a dispersion medium, in which the first electrode, the second electrode and the electrified body are disposed between the first substrate and the second substrate, and the liquid suspension is sealed between the first substrate and the second substrate, and the light control particles are capable of being accumulated to a periphery of the electrified body. Thus, it is possible to ensure uniformity of transmission light as well as to hold a light transmittance state in a state where the power supply is stopped.
