Abstract:
A head-up display device includes an illumination optical system, an imaging optical system and a reflective optical system. The illumination optical system emits a source light indicating information. The imaging optical system projects the source light to a projection surface. The reflective optical system has a dielectric multilayer film, and is configured so that a retardation of a subject wavelength including at least a part of wavelengths of the source light from the illumination optical system is in a range greater than −π/2 [rad] and smaller than π/2 [rad]. The reflective optical system is arranged on a path from the illumination optical system to the imaging system so that a polarization axis of the source light from the illumination optical system defines an angle α satisfying a relation of 0 degree <α<90 degrees <α<180 degrees, relative to an incident surface.

Claim (Index 2):
The head-up display device according to  claim 1 , wherein\n the subject wavelength includes a single wavelength having a strongest light intensity in a spectrum of the source light emitted by the illumination optical system and being incident on the reflective optical system, and the reflective optical system is configured so that the retardation of the subject wavelength is in the range greater than \u2212\u03c0/2 [rad] and smaller than \u03c0/2 [rad].
