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.
