Abstract
The invention relates to a head-up display system, in particular in the form of a head-up display system for displaying graphical elements on the windshield () of a motor vehicle, with a projection unit () arranged in the area of the front vehicle dashboard () of the motor vehicle, which is configured to emit preferably p-polarized light rays () preferably in the direction of a part of the windshield () providing a projection surface (), wherein the windshield () is configured to reflect the light rays emitted by the projection unit (). To enable a flexible adjustability of the reflection angle of the light rays incident on the windshield, to prevent the occurrence of the 'ghost' effect and to ensure a cost-effective production of the head-up display system and of the windshield, a nanostructure () formed of structural elements () is provided at least in the part of the windshield () providing the projection surface (), wherein the structural elements () are inclined at an angle of inclination (γ) in relation to a surface normal (N) of the windshield ().
