Abstract: A functional element having electrically controllable optical properties with side edges includes first and second carrier films having first and second flat electrodes and an active layer arranged flat between the first and second flat electrodes. A first and a second bus bar are arranged on at least one first side edge, the first and second carrier films have first and second recesses. The first bus bar is arranged on the surface of the second carrier film facing away from the second flat electrode and in the region of the second recess passes through the latter and contacts the first flat electrode electrically conductively. The second bus bar is arranged on the surface of the first carrier film facing away from the first flat electrode and in the region of at least one first recess passes through the latter and contacts the second flat electrode electrically conductively.

Abstract: A laminated pane includes an outer pane with an outer-side surface and an interior-side surface, a thermoplastic intermediate layer, an inner pane with an outer-side surface and an interior-side surface, a masking layer arranged between the outer and inner panes, an electrically switchable functional film switchable between a first switching state with lower optical transmission and a second switching state with higher optical transmission by applying an operating voltage. The electrically switchable functional film is arranged, when viewed perpendicularly through the laminated pane, directly adjacent to the masking layer or overlapping an opening in the masking layer. The masking layer and the electrically switchable functional film are arranged in one region of the laminated pane. The laminated pane includes a reflective layer for reflecting light on the outer-side surface and/or on the interior-side surface of the inner pane.

Abstract: A multilayer film having electrically controllable optical properties. The multilayer film has a first carrier film, a first planar electrode, an active layer having one or more layers in sequence, a second planar electrode, and a second carrier film, arranged one above the other in a planar manner. The first planar electrode and the active layer and optionally the second planar electrode are divided by at least one insulation line into at least two segments that are electrically insulated from one another. The insulation line is introduced with a laser through one of the carrier films and into the first planar electrode and the active layer and optionally the second planar electrode.

Abstract: A multilayer film having electrically controllable optical properties. The multilayer film has a first carrier film, a first planar electrode, an active layer having one or more layers in sequence, a second planar electrode, and a second carrier film, arranged one above the other in a flat manner. In a contact region, the first carrier film, the first planar electrode, and the active layer are removed, such that the second planar electrode is exposed. The contact region is designed in the shape of a strip with tapered ends.

Abstract: A composite pane includes an outer pane and an inner pane, which are connected to one another via a thermoplastic intermediate layer, wherein the composite pane has an opaque masking region and a transparent see-through region, wherein the intermediate layer has a functional element which covers the entire see-through region, wherein at least one region of the side edge of the functional element does not extend as far as the side edge of the composite pane but is arranged within the masking region, and wherein the surface of the outer pane facing away from the intermediate layer has a pattern of coated regions in the masking region which are provided with a partially transparent reflective coating.
