  • Patent number: 11002962
    Abstract: A light guide unit guides a display light toward a projection member. A multilayer film filter unit transmits the display light with an optical multilayer film and shields an external light incident from a projection window. In the XYZ color system, a first wavelength region is between a wavelength having a maximum value of a color matching function Z and a wavelength having a maximum value of a color matching function Y. A second wavelength region is between the wavelength having the maximum value of the color matching function Y and a wavelength having a maximum value of a color matching function X. A minimum transmittance of the multilayer film filter unit to the display light takes a minimum value among transmittances of respective wavelengths in a target wavelength region.
