Polarization device, method of manufacturing the same, liquid crystal device, and electronic apparatus

摘要

The wire grid type polarization device includes a substrate, and a metal layer formed on one face of the substrate in a substantially stripe shape in a plan view, a first dielectric layer provided on two side faces opposite to each other among a plurality of side faces of the metal layer and in a top part of the metal layer, and a second dielectric layer provided on the first dielectric layer. A substrate side end portion of the second dielectric layer is located between the one surface of the substrate and the top part of the first metal layerand a plurality of metal layers that includes a first metal layer having a first side face, a second side face opposed to the first side face, and a top part. First and second dielectric layers are provided in the first side face, the second side face, and the top part of the first metal layer. The first dielectric layer is provided between the first metal layer and the second dielectric layer. The optical absorption rate of the first dielectric layer is less than that of the second dielectric layer.
