Abstract

A shutter device includes: a substrate having an opening; a first light-shielding member that moves from a first position outside the opening of the substrate to a second position outside the opening to shield the opening, the second position being different from the first position; a second light-shielding member that partly shields the opening while moving from the first position to the second position; a first moving member that has a protrusion moving along a hole provided in the substrate to move the first light-shielding member; a second moving member that is coupled to the second light-shielding member and moves together with the second light-shielding member; and a third moving member, located outside a movement range of the protrusion during the second light-shielding member being located in the first position, that is coupled to the second light-shielding member and moves together with the second light-shielding member.
