Title:
COMBINER AND HEAD-UP DISPLAY DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/025741
Kind Code:
A1
Abstract:
The present invention provides a technology capable of reducing colored reflected light emitted from a combiner. A combiner (30) according to the present invention has a reflection surface (32) that reflects incident light. If the incidence angle is a first value that is 0° or more and 25° or less, the upper limit in a wavelength range is shorter than 700 nm when the reflectance is 90% of the peak reflectance for incidence light in a wavelength range between 400 nm and 700 nm, inclusive. If the incidence angle is a second value that is 60° or more and 85° or less, the wavelength is shorter than 570 nm when the reflectance is the peak for S-wave component in the incidence light in a wavelength range between 400 nm and 700 nm, inclusive.
