Abstract

Provided is a head up display for a vehicle. The head up display for the vehicle may include an imaging mechanism for emitting a linearly-polarized light in a first direction and a linearly-polarized light in a second direction orthogonal to the first direction, a first reflection mirror for reflecting a light to a windshield of the vehicle, a polarization reflection mirror spaced apart from the first reflection mirror wherein the polarization reflection mirror transmits the linearly-polarized light in the first direction and reflects the linearly-polarized light in the second direction, and a second reflection mirror spaced apart from the polarization reflection mirror wherein the second reflection mirror reflects the light transmitted through the polarization reflection mirror to the polarization reflection mirror. The imaging mechanism may include a separating partition for preventing mutual interference between the linearly-polarized light in the first direction and the linearly-polarized light in the second direction.
