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 5):
The head-up display device according to  claim 1 , further comprising:\n at least one retardation plate that is arranged on the path of the source light from the illumination optical system to the imaging optical system, and provides a retardation to orthogonal polarization components, wherein the retardation plate is arranged so that the angle of the polarization axis of the source light emitted by the illumination optical system relative to the incident surface of the reflective optical system is greater than 0 degree and smaller than 90 degrees, or greater than 90 degrees and smaller than 180 degrees.
