Abstract

A substrate includes first and second sides, the first side being flat, the second side including upper and lower sides, the lower side protruding from the upper side to form a step. An optical function layer is on a top of the substrate, the optical function layer including first and second end faces, the first end face being flush with the first side, the second end face being flush with the upper side of the second side. A first film continuously covers the first end face and the first side. A second film is different in reflectance from the first film, the second film continuously covering the second end face and the upper side. A first electrode is electrically connected to a top of the optical function layer. A second electrode is electrically connected to a bottom of the optical function layer.
