A vehicle display device (1) includes a display (5) that emits a display image projected on a windshield (103) as a display light (L), a reflective mirror (3) disposed on a light path of the display light (L) from the display (5) to the windshield (103) and reflects the display light (L), a reflective optical member (27) that is on a light path between the reflective mirror (3) and the display (5) and disposed facing the display (5), transmits the display light (L) emitted from the display (5) toward the reflective mirror (3), and reflects external light (SL) directed from the reflective mirror (3) toward the display (5), an optical sensor (9) that detects the external light (SL), and a controller (7) that executes temperature decreasing operation of the display (5) when the optical sensor (9) detects the external light (SL). The optical sensor (9) is disposed at a position to which the external light (SL) directed toward the display (5) via the reflective mirrors (3) is reflected by the reflective optical member (27) to be directed.
