1. A composite pane having electrically controllable optical properties, comprising an outer pane and an inner pane, which are joined to one another via a thermoplastic intermediate layer,
wherein an optoelectronic functional element having electrically controllable optical properties is embedded in the thermoplastic intermediate layer, which optoelectronic functional element comprises an active layer, with which transparent flat control electrodes are associated on both surfaces, between a first carrier film and a second carrier film, and
wherein a capacitive contact switching element is arranged between the active layer and the thermoplastic intermediate layer, in direct contact with the second carrier film facing in the direction of the inner pane.
