A head-up display includes a light source unit including first light source elements emitting lights of a first luminescent color and second light source elements emitting lights of a second luminescent color. The head-up display includes a first lens, a diffusion member, a spatial light modulation element that modulates the light emitted from the light source unit and transmitted through the first lens and the diffusion member, and an optical unit that projects the light emitted from the spatial light modulation element. The first lens changes an optical path of the light emitted from the light source unit, and the lights emitted from the first light source element and the second light source element are superimposed in a predetermined region on the incident surface of the spatial light modulation element.
