VEHICULAR ELECTROCHROMIC MIRROR REFLECTIVE ELEMENT

A vehicular interior electrochromic mirror reflective element includes a planar rear interior mirror-shaped glass substrate and a planar front interior mirror-shaped glass substrate. The front glass substrate is shape cut from a planar glass sheet. A perimeter seal establishes an interpane cavity between the rear glass substrate and the planar glass sheet at a respective planar front glass substrate portion of the planar glass sheet. An electrochromic medium is disposed in the interpane cavity. With the rear glass substrate joined with the respective planar front glass substrate portion of the planar glass sheet via the perimeter seal, the planar glass sheet is shape cut at the respective planar front glass substrate portion and the circumferential perimeter cut edges of glass substrates are processed to provide a circumferential rounded perimeter edge of the vehicular interior electrochromic mirror reflective element having a radius of curvature of at least 2.5 mm.
