1. A composite pane with at least one functional element, comprising:
a first pane comprising an inner side III and an outer side IV,
a second pane comprising an inner side II and an outer side I,
a thermoplastic intermediate layer that joins the inner side III of the first pane laminarly to the inner side II of the second pane,
at least one functional element that is incorporated into the thermoplastic intermediate layer,
wherein
the at least one functional element is directly adjacent the inner side III of the first pane and/or the inner side II of the second pane, and
a deaeration structure is mounted at least in regions of the at least one functional element, the deaeration structure being directly adjacent (a) the first pane such that no thermoplastic intermediate layer is present in said regions where the deaeration structure is mounted between the at least one functional element and the inner side III of the first pane and/or (b) the second pane such that no thermoplastic intermediate layer is present in said regions where the deaeration structure is mounted between the at least one functional element and the inner side II of the second pane, the deaeration structure preventing the at least one functional element from resting with its entire surface against the inner side II of the second pane and/or the inner side III of the first pane,
wherein the deaeration structure comprises a plurality of deaeration channels each having a width from 1 mm to 5 mm.
