Abstract
There are provided a linearly polarized light reflection film that has a high visible light transmittance, is capable of increasing the brightness of a display image, and is highly transparent in terms of appearance tint, a windshield glass, and a head-up display system. The linearly polarized light reflection film has a selectively reflecting layer in which an optically anisotropic layer and an isotropic layer are laminated. The selectively reflecting layer has at least one first reflection peak having a reflection center wavelength of 430 nm or more and less than 500 nm and having a reflectivity of 10% or more and 20% or less, at least one second reflection peak having a reflection center wavelength of 530 nm or more and less than 600 nm and having a reflectivity of 10% or more and 20% or less, and a third reflection peak having a reflection center wavelength of 600 nm or more and 800 nm or less, where two or more reflection peaks are present with a reflectivity of 10% or more and 20% or less or one reflection peak is present with a reflectivity of 10% or more and 20% or less and a wavelength width of 120 nm or more.
