Abstract

A functional layer includes a first backing film having a first electrically conductive coating, a second backing film having a second electrically conductive coating, and a liquid crystal array disposed between the two electrically conductive coatings. The first electrically conductive coating is exposed in a surface area and removed in the exposed surface area to form an insulation area to form at least a first segment and a second segment of the first electrically conductive coating, the first segment being electrically insulated from the second segment by the insulation area. A first electrically conductive conductor path extends from the first segment in the insulation area to a contact area. A first insulation layer is applied to the first electrically conductive conductor path and at least one second electrically conductive conductor path, which is applied to the first insulation layer, extends from the second segment to the contact area.
