Abstract
An optical element includes a substrate, a plurality of reflective reflection layers on the substrate, and an absorbing layer over the reflection layers. The reflection layers are arranged in a striped manner in plan view. The absorbing layer absorbs polarized light oscillating in the direction in which the reflection layers extend. The optical element also includes an oxide film on the substrate between the reflection layers and on the absorbing layer. The oxide film is formed by oxidizing the absorbing layer.
