Abstract
A head-up display comprises an image-generating unit which is protected from damage caused by incident light from the outside, a corresponding mirror element, and a method for the manufacture of the head-up display. The head-up display comprises an image-generating unit, a deflection unit and a mirror unit. The deflection unit comprises a mirror element that comprises a spectrally partially reflecting layer, disposed on a substrate, on which an absorptive polarization layer is disposed.
Claims13
1) A head-up display comprising:
- an image-generating unit;
- a mirror unit;
- a deflection unit having a mirror element having a spectrally partially reflecting layer disposed on a substrate, and
- an absorptive polarization layer disposed on the substrate, wherein the absorptive polarization layer allows light through that has the same polarization orientation as the polarization layer and absorbs light of a different polarization.

7) A method for the manufacture of a head-up display comprising:
- providing a substrate with a plane surface;
- vapor-depositing a spectrally partially reflecting layer onto the surface of the substrate;
- laminating an absorptive polarization layer onto the spectrally partially reflecting layer;
- and
- incorporating the mirror element obtained in this way into a deflection unit of the head-up display.
