Abstract
An electrochromic variable reflectance mirror for a vehicle includes a front element having a rear surface with a first layer of electrically conductive material disposed thereon, and a rear element having a front surface with a second layer of electrically conductive material disposed thereon. An electrical conductor may be provided to electrically couple a portion of the first conductive layer with a portion of the second conductive layer. At least one of the first and second conductive layers may be separated into a first portion and a second portion that is electrically isolated from the first portion and is in electrical contact with an electrochromic material disposed between the elements. A seal is provided to sealably bond the elements together in a spaced-apart relationship. The seal may have at least one electrically conductive region.
