Abstract
A rearview mirror element assembly includes an electrochromic reflective element having a front generally planar substrate and a rear generally planar substrate. A reflecting mirror reflector is established at a third surface of the rear substrate and an auxiliary mirror element is positioned rearward of a perimeter region of the front substrate. The auxiliary mirror element provides a wide angle view of a blind spot to the side of a vehicle and a generally planar portion of the electrochromic reflective element provides a generally planar view rearward of the vehicle. A perimeter band or demarcating band may be established at least partially around a perimeter border region of the substrate and may traverse the substrate at the perimeter region of the front substrate behind which the auxiliary mirror element is positioned. The band may demarcate the perimeter region from the generally planar portion of the reflective element.
