The invention relates to a projection surface (3) for a protection pane (4), in particular for a windshield of a motor vehicle, comprising: a first reflection surface (I) for preferably reflecting a light component of a projected image polarized in a first polarization manner and for preferably transmitting a light component of a projected image polarized in a second polarization manner, a second reflection surface (A) for reflecting a light component of the projected image polarized in the first polarization manner and for preferably transmitting a light component of a projected image polarized in the second polarization manner, a polarization means (34) arranged between the first reflection surface (I) and the second reflection surface (A) for changing a polarization of light passing through the projection surface (3) such that a light component of the second polarization manner passing through the first reflection surface (I) is changed into a light component of the first polarization manner and is reflect
