An exemplary shutter includes a chamber; a transparent, hydrophobic dielectric layer; a light-tight (i.e., non-transparent), insulating oily layer; a transparent conductive aqueous layer; and a pair of electrodes. The chamber has a pair of opposing transparent plates. The dielectric layer, the oily layer, and the aqueous layer are accommodated in the chamber, in that order, from one of the pair of transparent plates to the other. The pair of the electrodes is configured for generating an electric field to induce an electrowetting effect in the aqueous layer.
