Abstract
A composite pane with an HUD region and a sensor region is provided with an electrically conductive coating that reflects the p-polarized radiation of the HUD projector. The electrically conductive coating has precisely one electrically conductive layer based on silver, below which a lower dielectric layer or layer sequence with a refractive index of at least 1.9 is arranged and above which an upper dielectric layer or layer sequence with a refractive index of at least 1.9 is arranged. The ratio of the optical thickness of the upper dielectric layer or layer sequence to the optical thickness of the lower dielectric layer or layer sequence is at least 1.7. A busbar provided for connection to a voltage source is arranged on both sides of the sensor region and is connected to the coating such that a current path for a heating current is formed between the busbars.
