Abstract
Provided is a shutter device including a coil layer that includes one or more substrates having a through-hole formed in the center thereof and a coil installed thereon, the coil generating a magnetic field when a current is applied; and a shutter layer that is installed on one surface of the coil layer and includes a shutter case having a shape corresponding to the substrate and a pair of shutter blades which are connected to flexible suspensions formed in the shutter case, respectively. The shutter blades open and close the through-hole of the substrate, while being moved in the reverse direction to each other by an electromagnetic force caused by an interaction with the magnetic field generated by the coil and returning to the original position due to the recovery force of the flexible suspensions when the electromagnetic force is canceled.
