Claim 0:
1. A composite pane having a functional element that can be switched in segments and that has electrically controllable optical properties, comprising a first pane, and a second pane, which are joined to one another via an intermediate layer, and a functional element with a plurality of side edges, which is embedded in the intermediate layer,, wherein
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 at least one 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,
at least one second busbar electrically conductively contacts the second surface electrode, and, wherein, a length of a first busbar, along the segment associated therewith, exceeds a width of the segment, and first busbars, which contact segments adjacent one another, are arranged at opposite side edges of the functional element, and wherein the first busbars adjacent one another at a common side edge are electrically separated from one another by separating lines.
