Abstract: The present invention provides a heat ray cutting film comprising, on a substrate, at least two layers of a light reflecting layer X1 and a light reflecting layer X2 obtained by fixing cholesteric liquid crystalline phases, and an infrared ray absorbing layer comprising composite tungsten oxide microparticles, wherein the light reflecting layer X1 and the light reflecting layer X2 reflect lights circularly polarized in directions opposite to each other, reflection center wavelengths of the light reflecting layer X1 and the light reflecting layer X2 are within a range of 800 to 1100 nm and are substantially equal to each other, and total reflectivity of all light reflecting layers obtained by fixing cholesteric liquid crystalline phases is 80% or more. The heat ray cutting film of the present invention has high transparency and high heat shielding performance.

Abstract: A vehicle mirror having an image display function includes an image display device, a circularly polarized light reflection layer, and a front plate formed of glass or plastic in this order. The circularly polarized light reflection layer includes a linearly polarized light reflection plate and a 1/4 wavelength plate from a side of the image display device. The linearly polarized light reflection plate and the 1/4 wavelength plate are directly in contact with each other, or only an alignment layer is included between the linearly polarized light reflection plate and the 1/4 wavelength plate. A method for producing the vehicle mirror includes forming the 1/4 wavelength plate from a composition that is directly applied to the surface of the linearly polarized light reflection plate or that is directly applied to the surface of the alignment layer directly in contact with the linearly polarized light reflection plate.
