Abstract: A display device includes a light source, an optical system, a liquid crystal panel, and a first heat sink. The optical system converts light emitted from the light source into irradiation light that is to be an irradiation area having a predetermined width. The liquid crystal panel receives the irradiation light. The first heat sink includes an opening through which the irradiation light passes, and supports the liquid crystal panel. The first heat sink is in contact with the liquid crystal panel
