偏光板及び光学機器
Document Type and Number:
Japanese Patent JP7356291
Kind Code:
B2
Abstract:
This polarizer is a polarizer having a wire grid structure that includes a transparent substrate, a dielectric film which extends across one surface of the transparent substrate and has a lower refractive index than the transparent substrate, and a plurality of projections which extend in a first direction on top of the dielectric film and are arrayed periodically at a pitch that is shorter than the wavelength of the light in the used light region, wherein the transparent substrate has a thermal conductivity of at least 10 W/m·K but not more than 40 W/m·K, the plurality of projections each have, in order from the side closer to the dielectric film, a first dielectric layer, a reflective layer and a functional layer, the reflective layer contains a metal or a metal compound, and the functional layer is formed from a material different from the reflective layer.
