Abstract

Official abstract text for this publication.

A polarizer is provided comprising: a transparent substrate, on a main surface of which a plurality of grooves in parallel with each other are provided at an interval; a birefringence crystal layer with a single orientation formed on the main surface of the transparent substrate where the grooves are provided, wherein the birefringence crystal layer is at least filled in the grooves so that linearly polarized light incident on a location corresponding to the grooves and passing through the polarizer is converted into first polarized light, and linearly polarized light incident on a location between the grooves and passing through the polarizer is converted into second polarized light, the polarization directions of the first and the second polarized light are different from each other.

First claim

Opening claim text (preview).

What is claimed is: 1. A polarizer, comprising: a transparent substrate, on a main surface of which a plurality of grooves in parallel with each other are provided at an interval, the grooves being directly formed in the transparent substrate, and a part of the transparent substrate between the grooves and a part of the transparent substrate below the grooves being integrally formed; a birefringence crystal layer with a single orientation formed on the main surface of the transp…
