Patent ID: 10962698

Abstract:
Provided is inorganic polarizing plate, including in order of reciting: a substrate transparent to light in a bandwidth used; a first dielectric layer; a plurality of linear metal layers; a plurality of linear second dielectric layers; and a plurality of linear light absorbing layers, wherein the plurality of linear metal layers are arranged on the first dielectric layer at intervals shorter than a wavelength of the light, the plurality of linear second dielectric layers are arranged on the plurality of linear metal layers, respectively, the plurality of linear light absorbing layers are arranged on the plurality of linear second dielectric layers, respectively, and the inorganic polarizing plate includes a water repelling layer at peripheral ends of the inorganic polarizing plate at which longer-direction ends of the linear metal layers are present, to cover longer-direction ends of the linear metal layers, linear second dielectric layers, and linear light absorbing layers.
