SWITCHABLE FILM, LAMINATED GLAZING, AND METHOD OF PRODUCING SWITCHABLE FILM

A switchable film sequentially includes a first substrate; a first conductive layer; a switchable material layer; a second conductive layer; and a second substrate. The first substrate includes a first cut out portion wherein the first cut out portion aligns entirely with the second substrate. A first busbar is formed on the first conductive layer on the first substrate and a second busbar is formed on the second conductive layer on the second substrate within the first cut out portion of the first substrate. A first barrier is positioned around the first cut out portion of the first substrate.
