Reflective light control element with diffusible reflecting surface

摘要

A reflective photochromic element having a diffuse reflective surface is provided. A diffuse reflection type photochromic element has a transparent thin film having surface irregularities formed on a transparent base and a reflective photochromic thin film layer having surface irregularities formed on that transparent thin film. A diffuse reflection type photochromic glass material includes the aforementioned diffuse reflection type photochromic element as a constituent unit. A method for manufacturing a diffuse reflection type photochromic unit includes the steps of forming a transparent thin film having surface irregularities integrally or separately on a transparent base and forming a reflective photochromic thin film layer having surface irregularities on that transparent thin film.
