摘要: The present invention provides a reflection member including a selective reflection layer; and two ¼ wavelength phase difference plates, in which the selective reflection layer is disposed between the two ¼ wavelength phase difference plates, the selective reflection layer includes a layer of a fixed cholesteric liquid crystal phase having a central wavelength of selective reflection at a visible light range wavelength λi, and the selective reflection layer includes a layer in which a twisted direction of a helix of a cholesteric liquid crystal is only one of right or left as the layer of a fixed cholesteric liquid crystal phase having selective reflection at the wavelength λi. The reflection member of the present invention can be used particularly as a heat shielding member, which can reduce damage to the optical systems due to external light including visible light while efficiently extracting projected light.

摘要: A laminated body sequentially includes a substrate, an adhesive layer, and a multilayer film. The laminated body has characteristics of transmitting first polarized light and reflecting second polarized light having a polarization axis x that intersects a polarization axis y of the first polarized light. The multilayer film includes a plurality of first layers formed of a crystalline naphthalenedicarboxylic acid polyester and a plurality of second layers formed of a polymer other than the crystalline naphthalenedicarboxylic acid polyester, the first layers and the second layers being alternately stacked on top of each other. The first layers have a higher refractive index than the second layers on the polarization axis of the second polarized light, and the multilayer film has a thermal expansion coefficient of −80 [10−6/K] or more at a temperature 3° C. higher than a glass transition point of the multilayer film in the polarization axis direction of the first polarized light.
