Patent attributes
A plurality of vehicular electrochromic mirror reflective elements includes first and second vehicular electrochromic mirror reflective elements, each having a respective planar rear glass shaped substrate and a respective planar front glass substrate. The planar front glass shaped substrates are cut out from a planar glass sheet. Each planar rear glass shaped substrate is joined with a respective planar front glass substrate portion of the planar glass sheet via a respective perimeter seal. With the planar rear glass shaped substrate joined with the planar front glass shaped substrate, the circumferential perimeter cut edge of the planar front glass shaped substrate and the circumferential perimeter cut edge of the planar rear glass shaped substrate are processed to provide a circumferential rounded perimeter edge of the respective vehicular electrochromic mirror reflective element having a radius of curvature of at least 2.5 mm.
