Abstract
A method of manufacturing a reflective element for a vehicle rearview mirror assembly includes providing front and rear glass substrates and establishing an uncured trace material at least at the rear glass substrate and establishing an uncured seal material along a perimeter region of at least one of the second surface of the front glass substrate and the third surface of the rear glass substrate. The front and rear glass substrates are joined with the uncured seal material disposed therebetween. The uncured seal material and the uncured trace material are cured via a common curing process. The curing of the uncured trace material forms an electrically conductive trace at the rear glass substrate and the curing of the uncured seal material forms a perimeter seal of the reflective element. The electrically conductive trace is in electrical continuity with the electrically conductive mirror reflector.
