A head-up display for a transport comprising an image generating unit for generating an image, and an optical unit for projecting the image through a mirror unit is disclosed. The imaging unit comprises a folding mirror arranged between a light source and a display element. The light source radiates light, at a work angle to the propagation direction of the light incident on the folding mirror. The folding mirror has microstructures that have first mirror surfaces arranged at a first angle that deviates from the work angle of the folding mirror, and are spaced apart from one another to form gaps, wherein second surfaces are arranged in the gaps at a second angle. A polarizer guides light having a first polarization to the display element and light having a second polarization into the gaps. A retarder converts the polarization of the light guided into the gaps to the first polarization.
