A head-up display includes a picture generation unit configured to emit first light for generating a first picture at a position away from a vehicle by a predetermined distance and second light for generating a second picture at a position away from the vehicle by a distance different from the predetermined distance; and a reflection unit configured to reflect the first light and the second light so that the first light and the second light are radiated to a windshield. A first optical element that reduces transmittance of light including at least visible light to be lower than transmittance of the first light is provided between the picture generation unit and the windshield at a position through which the second light passes.
