    Abstract: A projection assembly for a head-up display (HUD), includes a composite pane, including an outer pane and an inner pane that are joined to one another via a thermoplastic intermediate layer, the composite pane having an HUD region; an HUD reflection layer suitable for reflecting p-polarized radiation, on the surface of the outer pane or of the inner pane facing the intermediate layer or within the intermediate layer; an HUD projector that is directed at the HUD region and that emits p-polarized radiation; and a high-refractive-index coating having a refractive index of at least 1.7 on the surface of the inner pane facing away from the intermediate layer. The high-refractive-index coating is a sol-gel coating.

    Abstract: A laminated pane includes an outer and an inner pane each having an outer-side surface and an interior-side surface and a thermoplastic intermediate layer. The interior-side surface of the outer pane and the outer-side surface of the inner pane are connected to one another via the thermoplastic intermediate layer, a reflective layer is arranged in at least a first sub-region of the laminated pane on the interior-side surface of the inner pane directly adjacent to the surroundings, which reflective layer is configured to reflect p-polarized light of a light source, an opaque cover layer is arranged at least in a second sub-region of the laminated pane. Starting from the interior-side surface, the reflective layer includes an optically high refractive index layer with a refractive index of greater than or equal to 1.7 and an optically low refractive index layer with a refractive index of less than or equal to 1.6.
