Head-up displays on motor vehicles often have double images and interfering reflections on the windshield. To avoid these, arrangements of linear polarization filters or shutter foils are suggested, which have particularly high light transmission. Arrangements of filter plates on a combiner inside of the windshield are also advantageous.
