A head-up display device is provided with: a combined light output unit which outputs combined light obtained by combining light emitted by a plurality of light sources which emit light having different wavelengths; and a heat dissipator which dissipates heat emitted by the light sources. The head-up display device displays a virtual image by means of the combined light. The plurality of light sources include a first light source which operates in a first operation guaranteed temperature band, and second light sources which operate in a second operation guaranteed temperature band having an upper limit higher than that of the first operation guaranteed temperature band. The first light source is provided in a location on the heat dissipator having a higher heat dissipation characteristic than the locations of the second light sources.

Head-up display device

A second supporting section installed detachably on a supporting surface is connected to a first supporting section installed detachably on a head-up display, such that the supporting sections can move relative to each other. Receiving sections provided on the under side of the head-up display comprises receiving surface. The receiving surface faces the under side of the head-up display via a gap. The first supporting section comprises a inserting section. The inserting section is forced removably along the under side of the head-up display into the gap between the receiving surface and the under side of the head-up display. By means of the force fit of the inserting section into the gap, the under side of the head-up display engages with the upper surface of the first supporting section.
