Abstract

A laminated glass pane with a transparent functional film embedded between laminating layers, said functional film incorporating a recess, wherein in the area of the recess of the functional film is arranged a transparent auxiliary film whose thickness is essentially the same as the thickness of the functional film. To prevent faults in optical transmission in the area of the recess, the auxiliary film overlaps the edge of the recess at least slightly in some areas.
