an outer pane and an inner pane that are joined to one another via at least one thermoplastic intermediate layer, and
at least one light sensor with a light-sensitive surface that is arranged between the outer pane and the inner pane,
wherein
the light-sensitive surface faces the outer pane, and
a shadow mask that covers at least some portions of the light-sensitive surface is arranged between the light-sensitive surface and the outer pane such that only part of the light-sensitive surface is illuminated when light impinges perpendicularly to the shadow mask.
