Abstract

An improved functional element having electrically controllable optical properties includes a stack sequence formed of a first carrier film, a first surface electrode, an active layer, a second surface electrode, and a second carrier film, wherein the second carrier film is folded around the edge of the first carrier film at least at one side edge and seals an exit surface of the active layer at the side edge.
