Abstract: A functional element having electrically controllable optical properties having a plurality of side edges includes a stacking sequence having a first carrier film, a first planar electrode divided by an isolation line into at least two segments, an active layer, a second planar electrode, and a second carrier film, wherein on a first side edge in a first region, the second carrier film, the second planar electrode, and the active layer have a first cutback and in a second region, the first carrier film, the first planar electrode, and the active layer have a second cutback, a group of first bus bars electrically conductively contacts the first planar electrode, and each segment of the first planar electrode is electrically conductively contacted by a bus bar from the group of the first bus bars, and at least one second bus bar electrically conductively contacts the second planar electrode.

Abstract: A connection arrangement includes a composite pane composed of a first pane and a second pane, which are connected to an intermediate layer, two electrically conductive structures, in particular two mutually opposed surface electrodes of an electro-optical functional element that are arranged between the first pane and the second pane, and a flexible flat cable having electrical conductor tracks, includes a first connection region at a first end and on a first side of the flat cable, wherein the first connection region has a contact point of at least one conductor track, at least one second connection region at the first end and on the first side of the flat cable, wherein the second connection region has a contact point of at least one conductor track, and a third connection region with contact points of the conductor tracks at a second end of the flat cable.
