Abstract:
To provide an inorganic polarizing plate which, when used in structures having different used wavelength bands, can reduce reflectance by using a common structure, making it possible to achieve a predetermined light extinction ratio. The inorganic polarizing plate has a substrate that is transparent to light in a used bandwidth, a reflective layer that is composed of grids that are formed on one surface of the substrate with a pitch that is smaller than a wavelength of light in the used bandwidth, a dielectric layer that is stacked on the reflective layer, and an absorbing layer containing FeSi fine particles.
