Electrochromic mirror having variable reflectivity
First Claim
1. An electrochromic mirror comprising:
- a transparent substrate;
a transparent electrode film which is formed on the transparent substrate and has conductivity;
an electrochromic film which is formed on the transparent electrode film and can be colored by reduction;
a light reflecting film which is formed on the electrochromic film and which hydrogen atoms can permeate;
a support substrate which has a conductive part having conductivity formed on at least one surface thereof; and
an electrolytic solution containing at least hydrogen ions, and a reduction promoting agent including neutral molecules or negative ions which can be oxidized to promote a coloring of the electrochromic film by reduction.wherein the transparent substrate is located close to the support substrate such that the conductive part faces the light reflecting film, and the electrolytic solution is enclosed between the light reflecting film and the conductive part.
