Abstract
It is an object of the present invention to provide a projection image-displaying member having excellent suitability for polarizing sunglasses, a windshield glass, and a head-up display system. The projection image-displaying member has a first polarization converting layer, at least one selectively reflecting layer, and a second polarization converting layer in this order. The first polarization converting layer and the second polarization converting layer are layers formed by fixing a helical alignment structure of a liquid crystal compound. The number of pitches in the helical alignment structure and a film thickness satisfy all relational expressions below. When the first polarization converting layer has a number of pitches xand a film thickness y(unit: μm),0.3≤≤2.0 and (i)≥1.86+0.13. (ii) When the second polarization converting layer has a number of pitches xand a film thickness y(unit: μm),0.25≤≤2.0, (iii)≤1.37+5.5, and (iv)≥1.37+0.25. (v)
