Electrochromic mirror with high corrosion resistant film
First Claim
1. An electrochromic mirror comprising:
- a transparent substrate;
a first conductive film;
an anode or cathode compound film;
a solid electrolyte film;
a cathode or anode compound film; and
a second conductive film, these films being successively laminated on one surface of the transparent substrate, said second conductive film consisting of a laminate formed by laminating, from the side of the cathode or anode compound film, at least two layers of a high reflecting metal material film and a high corrosion resistant metal film; and
wherein the high reflecting metal material film is made of different material from the high corrosion resistant metal film;
wherein the high corrosion resistant metal film extends to the transparent substrate or to the vicinity of the transparent substrate along end surface of the high reflecting metal material film, the cathode or anode compound film, the solid electrolyte film and the anode or compound film.

Abstract
A solid type EC mirror with improved corrosion resistance of its reflecting metal film is provided. On one surface (i.e., rear surface as viewed from the side on which light is incident) of a glass substrate are successively laminated an ITO transparent electrode film and an EC device consisting of three layers of an anode compound film, a solid electrolyte film and a cathode compound film. On the surface thereof are further successively laminated a high reflecting metal material film and a high corrosion resistant metal film. Since the high reflecting metal material film is covered with the high corrosion resistant metal film, a corrosion prevention effect against corrosion by moisture permeating from outside is enhanced and an offset width of the EC mirror can be reduced and a range of effective field of view can be enlarged.
