    an electro-optic medium confined in said space the transmittance of said medium being variable upon the application of an electric field thereto;

    seal means extending around the entire periphery of said assembly and extending between said first and second elements adjacent said peripheral edges for spacing said elements apart and confining said electro-optic medium in said space;

    electrical means for applying an electric field to said electro-optic medium to cause variation in the light transmittance of said medium;

    a reflective coating on one of said front and rear facing surfaces of said second element adapted to reflect light incident thereon through said first element and said electro-optic medium; and

    a perimeter coating on at least one of a portion of said electrical means and one of said front and rear facing surfaces of said first element adjacent said peripheral edge of said first element for concealing said seal means and portions of said electrical means therebehind when said assembly is viewed from said first element toward said second element.
