Abstract

A projection assembly for a head-up display (HUD), includes a composite pane with an electrically conductive coating, and a projector. The radiation of the projector is predominantly p-polarized. The electrically conductive coating has a first surface region within a HUD region and a second surface region outside the HUD region. The electrically conductive coating has at least one sub-region within the first surface region. The electrically conductive coating in the first surface section within the HUD region can be obtained from the electrically conductive coating in the second surface section using a subtractive method.
