Abstract
An electro-optic element is provided that includes a first substrate having a first surface, and a second surface having a first electrically conductive portion disposed thereon. The element also includes a second substrate having a third surface, a fourth surface, and a second electrically conductive portion disposed on at least the third surface. A primary seal is between the second and third surfaces, wherein the seal and the second and third surfaces define a cavity. An electro-optic medium disposed in the cavity. In addition, the second surface further includes at least one indicia disposed thereon between the electro-optic medium and the second surface.
