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 4):
The head-up display device according to  claim 1 , wherein\n the subject wavelength includes a wavelength region that has a rate of a spectrum intensity to an intensity sum being equal to or greater than a preset value, the intensity sum being a sum of spectrum intensities in an evaluation spectrum obtained by multiplying a spectrum of the source light emitted from the illumination optical system by a color-matching function and being incident on the reflective optical system with a matching function, 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].
