Abstract
Anti-glare EC mirror comprises a transparent glass substrate with ITO film, IrO.sub.x film, SnO.sub.2 film, Ta.sub.2 O.sub.5 film, WO.sub.3 film and Al film in the order written. Because of this layer arrangement, SnO.sub.2 film insures an ample supply of water during the aging of IrO.sub.x film, thereby allowing the aging operation to be completed within a short period of time.

An anti-glare electrochromic mirror comprising in the following order:
- a transparent substrate;
- a transparent electroconductive film on top of said transparent substrate;
- an oxidatively coloring film having a first refractive index on top of said transparent electroconductive film;
- an interference suppressing film on top of said oxidatively coloring film;
- an electrolyte film having a second refractive index on top of said interference suppressing film;
- a reductively coloring film on top of said transparent electrolyte film;
- and
- a reflective film of a electroconductive material on top of said reductively coloring film;
- wherein
- said interference suppressing film has a refractive index intermediate said first and second refractive indices.
