A composite pane having a functional element having electrically controllable optical properties, includes a stack sequence of an outer pane, a first intermediate layer, a second intermediate layer, and an inner pane, the intermediate layers containing a thermoplastic polymer film having a plasticizer, a functional element having electrically controllable optical properties is arranged, at least in sections, between the first and second intermediate layers, and the functional element is a polymer dispersed liquid crystal functional element and includes a second stack sequence of a first carrier film, an active layer, and a second carrier film. An exit surface of the active layer is sealed, at least in sections, on a lateral surface of the functional element by a barrier layer. The barrier layer substantially prevents the diffusion of plasticizer through the barrier layer, and is produced by a vacuum-based thin-film deposition method.
