摘 要：
A display light projection unit (10) projects an image as a display light which includes multiple wavelengths in a visible region. A light guide unit (30) guides the display light from the display light projection unit toward a projection member. The light guide unit includes a multilayer film filter unit (40) which transmits the display light by using an optical multilayer film (44) and which is configured to shield an external light incident from a projection window. In the XYZ color system, a first wavelength region (WR1) is a wavelength region between a wavelength (λzm) having a maximum value of a color matching function Z and a wavelength (λym) having a maximum value of a color matching function Y, and a second
wavelength region (WR2) is a wavelength region between the wavelength (λym) having the maximum value of the color matching function Y and a wavelength (λxm) having a maximum value of a color matching function X. A minimum

摘 要 附 图：
transmittance is a transmittance of the multilayer film filter unit with respect to the display light and takes a minimum value among the transmittances of respective wavelengths in a target wavelength
region. The minimum transmittance in the first wavelength region is smaller than the minimum transmittance in the second wavelength region. 主权项：
