Abstract
An interior rearview mirror reflective element includes a front substrate connected with a rear substrate via a perimeter seal, whereby, when so connected, at least a portion of a circumferential outer edge of the rear substrate is inward of a circumferential outer edge of the front substrate and no portion of the rear substrate protrudes beyond the front substrate. A first electrical connection establishes electrical connection at the front substrate and a second electrical connection may establish electrical connection at the rear substrate. An electrically conductive perimeter hiding band is disposed around a border region of the front substrate and substantially hides the seal and the electrical connections from view by a driver normally operating the vehicle and viewing the reflective element when the interior rearview mirror assembly is normally mounted in the vehicle.
