A windscreen display system for a motor vehicle, the windscreen display system comprising:
- a head-up display device comprising:
- a projection device for emitting a projection light beam having a first item of image information in a direction of a display area of a windscreen, so that the projected light beam is reflected at the display area and is perceptible in an ocular area, and
- a transparent cover for protecting the projection device, wherein the transparent cover has a cover pane and an antireflective layer applied to one side or both sides of the cover pane, and
- a windscreen base display device configured to output a second item of image information via a display device, so that the second item of image information is reflected in a windscreen base area and the reflected second item of image information is perceptible in the ocular area, wherein:
- the windscreen base area is a portion of the windscreen,
- the display device outputs the second item of image information using light of a first polarization direction,
