Abstract
A vehicular display device includes a reflection-type hologram disposed inside a windshield of a vehicle and a projection device that projects display light toward the hologram. The hologram outputs the display light from the projection device as diffracted light that travels toward the eye range of the vehicle. The projection device is arranged such that display light reflected off the windshield travels in a direction different, from the direction toward the eye range in a vehicle width direction.
