Abstract
An interior rearview mirror assembly of a vehicle includes front and rear substrates with a perimeter seal that spaces said front substrate from said rear substrate and establishes an interpane cavity therebetween for an electrochromic medium. The front substrate has a front connecting portion that extends outboard from the perimeter seal and the rear substrate has a rear connecting portion that extends outboard from the perimeter seal. The front and rear connecting portions may be established partially along the same perimeter region of the reflective element or along adjacent perimeter regions of the reflective element. Electrical connection to the transparent electrically conductive coating at the second surface of the front substrate is established at the front connecting portion of the front substrate and electrical connection to the electrically conductive coating of the third surface of the rear substrate is established at the rear connecting portion of the rear substrate.
