A vehicle includes a windshield, a display panel, a virtual image optical system forming an optical path of an image light emitted from the display panel onto the windshield, an outer housing, and a control circuit to control the display panel. The outer housing includes an outer case accommodating the virtual image optical system and having the image display panel attached thereto, an upper cover from which the image light is emitted, and a bottom cover covering a bottom portion of the outer case and having fins on an outer surface thereof. The bottom cover accommodates the display panel and the bottom surface of the outer case when fixed to the outer case and the display panel to isolate them from an external space of the outer housing. A heat conductive portion having a thermal conductivity higher than that of air is between the control circuit and the bottom cover.
