Claim 0:
1. A laminated pane with electrically controllable optical properties, comprising an outer pane and an inner pane that are joined to one another via a thermoplastic intermediate layer,
wherein an optoelectronic functional element with electrically controllable optical properties is incorporated into the thermoplastic intermediate layer, the optoelectronic functional element comprising an active layer, to which transparent sheetlike control electrodes are assigned on both surfaces of the active layer, between a first carrier film and a second carrier film,
wherein the thermoplastic intermediate layer, which surrounds the optoelectronic functional element, and the first and second carrier films contain, in each case, thermoplastic material,
wherein at least one capacitive touch element is integrated into the optoelectronic functional element such that a portion of at least one control electrode of the optoelectronic functional element is separated and provided with a signal lead for detecting a capacitive touch or approach signal.
