Abstract

A liquid lens device is provided with a liquid lens and a fluid circuit. The liquid lens includes a cylinder having a plurality of ports formed on the circumferential surface, and first and second elastic members which cover the both end surfaces of the cylinder to form a lens chamber inside. The fluid circuit permits a liquid to flow into the lens chamber and discharge from the lens chamber through the ports.
