Abstract:
Provided is a phase plate having high phase compensation effect with low manufacturing cost, which is a device including a substrate and a thin film including laminated thin films of two or more types having different refractive indexes. The device performs phase compensation for an oblique incident polarized light ray, by using interference due to a high refractive index thin film and a low refractive index thin film.
