1. A rearview mirror assembly comprising:
- a housing;
a bezel; and
an electro-optic mirror element comprising;
a first substantially transparent substrate having an edge extending around at least a portion of a perimeter of the first substantially transparent substrate;
a second substantially transparent substrate, wherein the first and second substantially transparent substrates define a cavity; and
an electro-optic material disposed within the cavity,wherein the first substantially transparent substrate and at least one of the housing and bezel have a difference in coefficient of thermal expansion between about 5 ppm and about 50 ppm.

Abstract
A rearview mirror assembly includes a housing, a bezel, and an electro-optic mirror element. The electro-optic mirror element includes a first substantially transparent substrate having an edge extending around at least a portion of a perimeter of the first substantially transparent substrate and a second substantially transparent substrate. The first and second substantially transparent substrates define a cavity. An electro-optic material is disposed within the cavity. The first substantially transparent substrate and at least one of the housing and bezel have a difference in coefficient of thermal expansion between about 5 ppm and about 50 ppm.
