A head-up display includes: a plurality of light source elements which are arranged in a first direction and emit light; first lens which takes in from an incident surface the light emitted from the plurality of light source elements and emits the light from an emission surface; diffusion member disposed on a side of the emission surface of the first lens; a spatial light modulation element which takes in from an incident surface the light having been emitted from the plurality of light source elements and having passed through first lens and diffusion member, modulates the taken-in light in accordance with image information, and emits the modulated light from an emission surface; and an optical element which reflects the light emitted from spatial light modulation element. First lens changes an optical path of light emitted from each of light source elements such that the light emitted from the each of light source elements reaches the same area on the incident surface of spatial light modulation element.
