Abstract:
A composite pane with an electrically switchable functional element, includes first and second panes, a thermoplastic intermediate layer joining the first pane to the second pane and including a first laminating film with a thickness of at least 0.3 mm and a second laminating film with a thickness of at most 70 μm. The first laminating film is inserted substantially areally between the first and second panes. The second laminating film is inserted exclusively in the region of the at least one functional element and protrudes with an overhang x of at least 1 mm and at most 10 mm beyond the outer edges of the functional element. The direct layer sequence in the region of an electrically switchable functional element consists of the first pane, the second laminating film, the electrically switchable functional element, optionally, a further second laminating film, the first laminating film, and the second pane.
