    Abstract: Provided are a projection image display member having a high visible light transmittance, suppressing a double image of a display image, and having excellent suitability of polarized sunglasses for incident light reflected from external light, a windshield glass using the projection image display member, and a head-up display system. The problem is solved such that one or more phase difference layers, one or more selective reflection layers, and one or more polarization conversion layers are provided in this order, the polarization conversion layer being a layer in which a helical alignment structure of a liquid crystal compound is fixed, and the number of pitches x of the helical alignment structure and a film thickness y (μm) of the polarization conversion layer satisfying “0.3≤x≤7.0”, “0.5≤y≤6.0”, “y≤0.7x+3.2”, and “y≥0.7x−1.4”.

    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 x1 and a film thickness y1 (unit: μm), 0.3≤x1≤2.0 and  (i) y1≥1.86x1+0.13.  (ii) When the second polarization converting layer has a number of pitches x2 and a film thickness y2 (unit: μm), 0.25≤x2≤2.0,  (iii) y2≤1.37x2+5.5, and  (iv) y2≥1.37x2+0.25.  (v)

    Abstract: An object of the present invention is to provide a half-mirror film for displaying a projection image having high adhesiveness, a laminated glass in which wrinkle generation of the half-mirror film is suppressed or furthermore has high adhesiveness, and an image display system using the laminated glass. The problem is solved by providing a half-mirror film for displaying a projection image including a transparent support; and a selective reflection layer reflecting light in a wavelength selective manner, in which the transparent support has an absolute value of 10 nm or less of an in-plane phase difference at a wavelength of 550 nm and a heat seal layer disposed on an opposite surface of a surface having the selective reflection layer, the heat seal layer contains a thermoplastic resin, and a mixed layer in which components of the transparent support and the heat seal layer are mixed is formed between the transparent support and the heat seal layer.

    Abstract: A thin metasurface structure where a phase difference of transmitted electromagnetic waves is large and a transmittance with respect to the electromagnetic waves is also high. A metasurface structure that acts on electromagnetic waves having a frequency of 10 THz or less and is obtained by laminating a first structure layer where first metal microstructures are arranged, a second structure layer where second metal microstructures are arranged, a third structure layer where third metal microstructures are arranged, and a fourth structure layer where fourth metal microstructures are arranged to be spaced from each other.
