Abstract

A composite pane having an electrically controllable functional element that can be switched in segments, includes first and second panes joined to one another via an intermediate layer, and a functional element with a plurality of side edges embedded in the intermediate layer. The functional element includes, arranged flat one over another, a first surface electrode and a second surface electrode, between which an active layer is arranged flat. The first surface electrode is divided into multiple segments by a separating line. A group of first busbars electrically conductively contact the first surface electrode, and each segment of the first surface electrode is electrically conductively contacted by one busbar from the group of the first busbars. A second busbar electrically conductively contacts the second surface electrode.
