1. An electro-optic element comprising:

  • a first substrate having first and second surfaces;

    a second substrate having third and fourth surfaces, the second and third surfaces disposed in a parallel and spaced-apart relationship such to form a gap therebetween;

    a sealing material circumferentially disposed along a perimeter of the third surface to sealingly affix the second and third surfaces together to form a chamber therebetween; and

    an electro-optic medium in the chamber;

    wherein at least one of the second and third surfaces carries a first layer of a transparent conducting oxide (TCO);

    wherein the at least one of the second and third surfaces carrying the first layer additionally carries a second layer comprising a metal, the second layer being distinct from the first layer;

    wherein the second layer is substantially absent at at least a portion of a surface of the first layer to define an opening through the second layer, and the first layer is exposed at substantially all of the opening; and

    wherein the second layer has a sharp or abruptly terminated edge defining the opening.
