PURPOSE: To provide a holographic head-up display device capable of reducing flare from the outside of a vehicle. CONSTITUTION: This device has a combiner formed out of a hologram 22, and the exterior side of the hologram 22 has a wavelength selective reflecting film 10 formed so as to reflect light of such wavelength as diffracted with the hologram 22 along the incident direction of flare, and allow the transmission thereof in the case of vertical incidence on a windshield from the outside. |
