VEHICULAR ELECTROCHROMIC REARVIEW MIRROR ASSEMBLY

A vehicular electrochromic rearview mirror assembly includes a mounting structure and a mirror head. The mirror head accommodates an electrochromic mirror reflective element including front and rear glass substrates and an electrochromic medium disposed therebetween. The medium conductively contacts a transparent conductive coating at a second side of the front substrate and a conductive coating at a third side of the rear substrate. A conductive connector is disposed at a fourth side of the rear substrate and conductively connects to a conductive material along a perimeter region of the second side and the conductive coating at the third side. The perimeter region extends beyond an outer peripheral edge of the rear substrate. The conductive material is established in a zigzag pattern along the perimeter region so portions of the zigzag pattern are inboard and other portions are outboard of the edge of the rear substrate.
