Provided is a light control device that can easily eliminate adhering foreign matter. A light control device (100) has at least one substrate (20) wherein an opening part (21) (optical opening) is formed, at least one magnet (34) (rotational axis member) attached rotatably to the substrate (20), at least one drive blade (31) (light control part) joined to the magnet (34), and a coil (12) and the magnet (34) (drive part) for operating the drive blade (31), and rotates the drive blade (31) alternately to a first position and a second position by rotational motion of the magnet (34) by the coil (12) and the magnet (34) to control incident light passing through the opening part (21), wherein the device has the magnet (34), the coil (12), and a drive current source (101) (oscillation generating unit) that imparts mechanical oscillation to the drive blade (31) through a specific trajectory. |
