Abstract

A multilayer film with electrically switchable optical properties, includes arranged areally in the following order a first carrier film, a first electrically conductive layer, an active layer, a second electrically conductive layer, and a second carrier film. The multilayer film has within its area at least one first cutout and the at least one first cutout protrudes in the form of a through-hole through all layers of the multilayer film, the first cutout is filled with an electrically conductive filler compound, which electrically conductingly contacts the first electrically conductive layer within the first cutout, and a first busbar electrically conductingly contacts the electrically conducting filler compound.
