A heads up display (HUD) includes a display source for emitting an emitted image, a windshield and an absorbing polarizer. For substantially normally incident light, the absorbing polarizer substantially transmits the incident light polarized along a pass direction, and substantially absorbs the incident light polarized along a block direction. The emitted image includes at least one image ray that is received and transmitted by the absorbing polarizer toward the windshield at a first location of the absorbing polarizer. The transmitted image ray is received and reflected by the windshield at a second location of the windshield. A first normal line of the absorbing polarizer at the first location is substantially parallel to a projection of the transmitted image ray onto the windshield. Further, the pass direction of the absorbing polarizer at the first location is substantially parallel to a second normal line of the windshield at the second location.
