A projection arrangement for a head-up display (HUD) is presented. The arrangement has a vehicle windshield that includes an outer pane and an inner pane bonded to one another via a thermoplastic intermediate layer. The vehicle windshield has an upper edge, a lower edge, and an HUD region. The arrangement also has a projector that is aimed at the HUD region to generate a virtual image perceivable by an observer situated within an eyebox. According to one aspect, the windshield has an HUD reference point, at which a central beam running between the projector and the center of the eyebox strikes the inner pane. According to another aspect, the thickness of the thermoplastic intermediate layer in the vertical course between the upper edge and the lower edge in at least a section corresponding to the HUD region is variable according to a wedge angle.
