Provided are a linearly polarized light reflecting film, a windshield, and a head-up display system which have high visible light transmittance, can improve the brightness of a displayed image, and have good transparency of the appearance color. The linearly polarized light reflecting film has a selective reflection layer in which an optically anisotropic layer and an isotropic layer are laminated, and the selective reflection layer satisfies any of the following conditions: the selective reflection layer has at least one first reflection peak having a central reflection wavelength of 430 nm or more and less than 500 nm, and has a reflectance of 10% or more and 20% or less; a second reflection peak having at least one central reflection wavelength of 530 nm or more and less than 600 nm, and having a reflectance of 10% or more and 20% or less; and a third reflection peak having a center reflection wavelength of 600 nm to 800 nm inclusive, the third reflection peak having two or more reflection peaks and a reflectance of 10% to 20% inclusive, or the third reflection peak having one reflection peak and a reflectance of 10% to 20% inclusive and a wavelength bandwidth of 120 nm or more.

    提供一种具有高可见光透射率并且能够提高显示图像的亮度、外观颜色的透明性良好的线偏振光反射膜、挡风玻璃及平视显示器系统。所述线偏振光反射膜具有将光学各向异性层和各向同性层层叠而成的选择反射层,选择反射层满足以下任一条件:具有至少一个中心反射波长为430nm以上且小于500nm的第一反射峰,反射率为10%以上20%以下;具有至少一个中心反射波长为530nm以上且小于600nm的第二反射峰,反射率为10%以上20%以下;具有中心反射波长为600nm以上800nm以下的第三反射峰,第三反射峰具有两个以上的反射峰且反射率为10%以上20%以下,或者反射峰为一个,反射率为10%以上20%以下且波长带宽为120nm以上。
