Abstract

An electrochromic mirror comprising a glass substrate, a transparent conductive film formed on the back of the glass substrate, an electrochromic layer formed on the back of the transparent conductive film, a reflection and electrode film formed on the back of the electrochromic layer in which the electrochromic layer and the reflection and electrode film are covered on the back thereof with an ion insulative oxide film, whereby the performance is stabilized and the productivity enhanced.

Claims

1. An electrochromic mirror comprising a glass substrate, a transparent conductive film formed on the back of the glass substrate, an electrochromic layer formed on the back of the transparent conductive film, a reflection and electrode film formed on the back of the electrochromic layer, wherein the electrochromic layer and the reflection and electrode film are covered from the back thereof with an ion insulative oxide film.

2. An electrochromic layer according to claim 1, wherein the ion insulative oxide film comprises Al₂O₃ or Ta₂O₅.

3. An electrochromic layer according to claim 1, wherein an ion insulative oxide film is interposed between the electrochromic layer and the glass substrate.

4. An electrochromic layer according to claim 1, wherein a portion of the electrochromic mirror excepting for the glass substrate is covered with a corrosion inhibitive coating layer.
