Abstract
Provided is a vehicular heads-up display device with which it is possible to avoid burn-in of an internal component upon a reflecting member by exterior light, improving display quality. A vehicular heads-up display device, comprising a case body (50) whereon an aperture part (51c) is disposed and a light-emitting body (30) that is housed within the case body (50) reflects emitted light L that is emitted by the light-emitting body (30) externally to the case body (50) via the aperture part (51c) and reflects said emitted light L from the windshield (13), causing the driver (14) to have sight of the virtual image V that is obtained by said reflection. The vehicular heads-up display device further comprises a semi-transmissible cover (55) installed in the aperture part (51c), and a dispersal means (58) is disposed between the light emitting body (30) and the cover (55), for dispersing exterior light that enters the case body (50) via the cover (55).
