A head-up display for a vehicle includes a light source, a display panel, and an illumination optical system. The display panel is of a transmissive type. The illumination optical system guides illumination light from the light source to the display panel. The illumination optical system includes a lens module. The lens module includes one or more lenses positioned on an optical axis of the illumination light. The light source is configured to emit the illumination light in which beams forming a larger angle with respect to the optical axis have lower brightness. The lens module has an optical property whereby, in the illumination light beams which form a larger angle with respect to the optical axis are transmitted with increased density.
