Abstract
An electro-optic mirror reflective element for a rearview mirror assembly for a vehicle includes a front substrate and a rear substrate. A surface of the front substrate and a surface of the rear substrate oppose each other and are spaced apart by a perimeter seal, with an electro-optic medium disposed between the surfaces and bounded by the perimeter seal. A transparent electrically conductive coating is established at the surface of the front substrate, and a specularly reflective mirror reflector is established at the surface of the rear substrate. The specularly reflective mirror reflector includes a stack of thin film layers having (i) an environmentally stable electrically conductive metallic reflecting thin film layer, (ii) an environmentally vulnerable electrically conductive metallic reflecting thin film layer and (iii) a transparent electrically conductive thin film layer. The transparent electrically conductive thin film layer includes aluminum doped zinc oxide.
