Head-up display, which is mounted on a vehicle, performs projection on a transparent reflective member, and allows an observer to visually recognize a virtual image, includes display device that displays an image, and a projection optical system that has refractive optical system and projects displayed image displayed by display device on eye box of the observer. As an angle formed between a vector of a light beam that is incident on refractive optical system and a vector of an output light beam, the angle is greater at a light beam on an image end passing through a vehicle inner side of refractive optical system than at a light beam on an image end passing through a vehicle outer side of refractive optical system.
