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.

Abstract: A ghost is reduced while improving the sensitivity. A scintillator has a plurality of columnar crystals formed of thallium-activated cesium iodide, and converts X-rays into visible light and emits the visible light from the distal end of the columnar crystal. The photoelectric conversion panel has a plurality of photodiodes formed of amorphous silicon to generate electric charges by detecting the visible light emitted from the scintillator. Assuming that the maximum emission intensity of the scintillator is I1, a wavelength at which the maximum emission intensity is obtained is WP, and the emission intensity at a wavelength of 400 nm is I2, I2/I1≧0.1 and 540 nm≦WP
