    摘要： 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 x 1 and a film thickness y 1 (unit: µm),
    (i) 0.3 ≤ x 1 ≤ 2.0 and
    (ii) y 1 ≥ 1.86x 1 + 0.13.
    When the second polarization converting layer has a number of pitches x 2 and a film thickness y 2 (unit: µm),
    (iii) 0.25 ≤ x 2 ≤ 2.0
    (iv) y 2 ≤ 1.37x 2 + 5.5, and
    (v) y 2 ≥ 1.37x 2 + 0.25.
