摘要： A polarization element includes a plurality of metallic thin lines that extend in one direction on one surface of a substrate, a protecting layer that is provided on the plurality of metallic thin lines, and a cavity portion that is surrounded by two metallic thin lines which are adjacent to each other, the substrate, and the protecting layer. Each end portion of the plurality of metallic thin layers has a forward tapered shape in a cross-section parallel to the one direction, and the protecting layer extends from the upper portion of the plurality of metallic thin lines to the one surface of the substrate through each end portion.

摘要： A wire grid polarization apparatus includes a plurality of wire-shaped metal layers arranged in parallel to each other in a region, on which light is incident, on a side of a first surface of a transmissive substrate. The wire-shaped metal layers include aluminum or silver as a principal component. Outside the region, a sacrificial electrode having an ionization tendency greater than an ionization tendency of the wire-shaped metal layers is electrically coupled to the wire-shaped metal layers. This allows the sacrificial electrode to prevent the wire-shaped metal layers from being corroded under a condition of high temperature and high humidity. Being provided outside the region, the sacrificial electrode does not impair polarization separation performance.

摘要： A light-emitting device includes a substrate, a laminated structure provided at the substrate, and a conductive layer provided at the laminated structure and configured to apply an electric current to the laminated structure. The laminated structure is provided between the substrate and the conductive layer, and includes a first semiconductor layer of a first conductive type, a second semiconductor layer of a second conductive type different from the first conductive type, and a light-emitting layer provided between the first semiconductor layer and the second semiconductor layer. The conductive layer includes a plurality of wire portions extending in a direction orthogonal to a lamination direction of the laminated structure, and is configured to polarize light generated at the light-emitting layer, and an electric current is applied to the light-emitting layer via the plurality of wire portions.
