1. An electrochromic variable reflectance mirror for automotive vehicles, comprising:

  • front and rear spaced elements, each having front and rear surfaces, said rear surface of said front element having a layer of transparent conductive material disposed thereon, and said front surface of said rear element having at least one layer of a conductive reflector/electrode material disposed thereon, where said front and rear spaced elements are sealably bonded together in a spaced-apart relationship to define a chamber therebetween, said chamber containing an electrochromic reversibly variable transmittance medium in contact with said transparent conductive material and said reflector/electrode;

    an information display area disposed within said reflector/electrode having areas containing reflector/electrode and areas substantially devoid of reflector/electrode; and

    a display that is juxtaposed with said rear surface of said rear element and aligned with said information display area;

    where said reflector/electrode material is effective to reflect light through said medium and said front element when said light reaches said reflector/electrode after passing through said front element and said medium.
