1. A method for forming a window, comprising:
coating a first transparent substrate with a first liquid crystal layer;
coating a second transparent substrate with a second liquid crystal layer; and
in a vacuum chamber, pressing the first and second substrates together, wherein the first and second liquid crystal layers are separated from one another by a conductive adhesive having a first surface contacting the first liquid crystal layer and a second surface contacting the second liquid crystal layer and wherein the conductive adhesive has a refractive index that differs from a refractive index of the first and second liquid crystal layers by less than 0.15.
