Abstract:
1. A polarizing element comprising: a substrate; a plurality of reflection layers that are arranged in a band shape at a predetermined interval on the substrate; dielectric layers that are formed on the plurality of reflection layers; and inorganic micro-particle layers that are formed on the dielectric layers by inorganic micro-particles having shape anisotropy in which a length of a diameter of the inorganic micro-particles in a band shape arrangement direction of the plurality of reflection layers is longer than a length of a diameter of the inorganic micro-particles in a direction orthogonal to the band shape arrangement direction of the plurality of reflection layers, wherein at least one of the inorganic micro-particle layers, when viewed in a cross-sectional view orthogonal to the band shape arrangement direction of the plurality of reflection layers, has a first convex portion toward a side of a first adjacent reflection layer adjacent to one reflection layer and a second convex portion toward a side of a second adjacent reflection layer adjacent to the one reflection layer, wherein the first convex portion and the second convex portion are separated by at least one concave portion in the inorganic micro-particle layers.
