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: There are provided a screen image-displaying laminated glass that reduces the distortion of a projected display image, a method for producing the screen image-displaying laminated glass, and a screen image display system including the screen image-displaying laminated glass. The screen image-displaying laminated glass has a half-mirror film that has a transparent support and that has a selectively reflecting layer which wavelength-selectively reflects light, a first glass plate disposed on one surface of the half-mirror film, and a second glass plate disposed on the other surface of the half-mirror film. The longitudinal directions of bright and dark lines observed by a magic mirror method match each other at the first glass plate, the second glass plate, and the transparent support.

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.
