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 1):
A head-up display device that is to be mounted to a movable body, the head-up display device comprising:\n an illumination optical system being configured to emit a source light indicating information; an imaging optical system in which the source light emitted by the illumination optical system is projected to a projection surface; and a reflective optical system\n being arranged on a path of the source light from the illumination optical system to the imaging optical system such that a polarization axis of the source light emitted from the illumination optical system defines an angle relative to an incident surface of the reflective optical system, the angle being greater than 0 degree and smaller than 90 degrees, or being greater than 90 degrees and smaller than 180 degrees, \n having a dielectric multilayer film that transmits an electromagnetic wave in an infrared region and reflects an electromagnetic wave in a visible light region, and \n being configured so that a retardation of a subject wavelength including at least a part of wavelengths of the source light emitted by the illumination optical system is in a range greater than \u2212\u03c0/2 [rad] and smaller than \u03c0/2 [rad].
