Head-up display includes display device, projection optical system, a polarization member, and a first polarizer. Display device displays an image. Projection optical system includes refraction lens. Projection optical system projects the image displayed on display device to an observer. The polarization member is disposed between projection optical system and a reflection member that reflects light from projection optical system. Transmittance of the polarization member depends on a polarization direction of transmitted light. The first polarizer is disposed behind refraction lens on an optical path starting from display device. The first polarizer rotates a predetermined polarized component by a quarter of wavelength.
