Abstract
To allow an electrochromic device to have little or no offset between its front and rear elements, an electrical conductor may be provided to electrically couple a portion of a first conductive layer provided on the rear surface of the front element with a portion of a second conductive layer provided on the front surface of the rear element. The electrical conductor may be in the form of a conductive portion of the seal. To prevent shorting across the electrochromic medium, at least one of the first and second conductive layers is separated into a first portion and a second portion that is electrically isolated from the first portion and is in electrical contact with the electrochromic material. An elastomeric bezel may be utilized. Also, an edge seal may optionally be employed so as to reduce the need or width of the bezel.
