Abstract: A head-up display may comprise: a picture generation unit having an emission surface from which image light is emitted; a half-wavelength phase retarder disposed to face a first area of the emission surface; a first flat mirror configured to reflect image light emitted from a second area of the emission surface; a second flat mirror configured to reflect image light emitted from the half-wavelength phase retarder; and a concave mirror configured to reflect each of the image light reflected by the first flat mirror and the image light reflected by the second flat mirror to a window shield.
