Abstract

A head up display arrangement for a motor vehicle includes a head up display projector including a lens with a polarizer. The head up display projector emits a linearly polarized light field via the lens. A windshield reflects the light field such that the reflected light field is visible to a human driver of the motor vehicle as a virtual image. The windshield includes an outer plastic layer sandwiched between a half-wave plate and an outer glass layer. An inner plastic layer is sandwiched between the half-wave plate and an inner glass layer.
