Abstract
A reflector includes a reflection substrate and an optical diffusion layer deposited on the reflection substrate, which is provided with a plurality of reflection inclined planes continuously formed on a surface thereof with a stripe geometry in plan view and a surface of each refection inclined plane is an irregular irregular surface, and the optical diffusion layer is made of a matrix of a transparent resin or a transparent adhesive having fine particles dispersed therein so as to flatten the reflection substrate.
