1. A method for producing a composite pane, comprising arranging a functional element in a recess of a thermoplastic frame film, arranging the thermoplastic frame film along with the functional element between a first glass pane and a second glass pane to form a layer stack, and subsequent joining of the layer stack to form a composite pane by lamination, wherein the thermoplastic frame film and the functional element have a different thickness and the different thickness is at least partially compensated by at least one thermoplastic compensating film, whose thickness is less than twice as large as a difference between the thicknesses of the thermoplastic frame film and the functional element such that a maximum offset in the layer stack is less than the difference between the thicknesses of the thermoplastic frame film and the functional element, wherein the thickness of the thermoplastic frame film is greater than the thickness of the functional element and wherein the thermoplastic compensating film is arranged on the functional element within the recess, wherein the functional element is a multilayer element which includes an active layer arranged between two transparent surface electrodes formed on insulating transparent polymeric carrier layers.
