Abstract: There are provided a projection image-displaying member, a windshield glass, and a head-up display system in which both high visible light transmittance and good tint of a screen image displayed are achieved. The projection image-displaying member has a selectively reflecting layer that wavelength-selectively reflects light. The selectively reflecting layer has a maximum reflectivity in a wavelength range of 700 to 850 nm at an incidence angle of 5° and has a peak with a reflectivity of 15% or more in a wavelength range of 470 to 540 nm. The selectively reflecting layer further has two or more peaks of reflectivity in a wavelength range of 540 to 700 nm.
