Abstract

Electrochromic mirrors comprises a transparent conductive substrate, a reflective conductive substrate, and an ion conductive layer disposed therebetween wherein at least one of said substrates is provided on the peripheral portions of its conductive surface with a highly conductive layer having smaller resistance than the surface resistance of said conductive surface.

Claims

1. An electrochromic mirror comprising a transparent conductive substrate, a reflective conductive substrate, and an ion conductive layer disposed therebetween, wherein at least one of said substrates is provided on the peripheral portion of its conductive surface with a highly conductive layer having a lower resistance than the surface resistance of said conductive surface.

2. The electrochromic mirror according to

claim 1

wherein at least one of said substrates is provided on the peripheral portion of the conductive surface side and/or the end surfaces of the conductive surface with said highly conductive layer.

3. The electrochromic mirror according to

claim 1

wherein said highly conductive layer is provided at least on the peripheral portion of the conductive surface of said transparent conductive substrate.

4. The electrochromic mirror according to

claim 1

wherein said highly conductive layer is provided in the neighborhood of the peripheral edge of the conductive surface of said substrate.

5. The electrochromic mirror according to

claim 1

wherein said two conductive substrates are joined at their periphery with a sealant by which said highly conductive layer is separated from said ion conductive layer.

6. The electrochromic mirror according to

claim 1

wherein said ion conductive layer contains an electrochromic compound.
