1. A rearview mirror element for use in a vehicle, comprising:
- a first substantially transparent substrate and a second substrate secured in a spaced apart relationship with respect to one another to form a chamber there between, said second substrate comprising a layer of reflective material at least approximately 200 Å
thick comprising silver proximate a surface of said second substrate closest to said first substantially transparent substrate and a first layer of substantially transparent conductive material less than approximately 300 Å
comprising indium tin oxide positioned between said layer of reflective material and said first substantially transparent substrate, wherein the rearview mirror element exhibits at least 35% reflectivity.

Abstract
According to one embodiment of the present invention, an electrochromic rearview mirror assembly for a vehicle includes an electrochromic mirror having a variable reflectivity, a glare sensor for sensing levels of light directed towards the front element from the rear of the vehicle, an ambient sensor for sensing levels of ambient light, a display positioned behind the partially transmissive, partially reflective portion of the reflector for displaying information therethrough.
