    摘要： The half mirror includes a retardation layer, a circularly polarized light reflecting layer, and a front panel that are disposed in this order. The retardation layer has a front phase difference as measured at a wavelength of 500 nm of 107 to 127 nm and a front phase difference as measured at a wavelength of 475 nm of 110 to 130 nm. The circularly polarized light reflecting layer includes three cholesteric liquid crystal layers. The three cholesteric liquid crystal layers have different selective reflection center wavelengths λ1, λ2, and X,3. The center wavelengths λ1, λ2, and λ3 satisfy 380 nm

    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： The present invention provides a reflection film, comprising a right circularly-polarized light reflection layer and a left circularly-polarized light reflection layer as circularly-polarized light reflection layers, each of the circularly-polarized light reflection layers consisting of a layer obtained by fixing a cholesteric liquid-crystalline phase, having a reflection wavelength at which a diffuse reflectance for non-polarized light becomes 50% or more in a wavelength region in which each of the circularly-polarized light reflection layers exhibits selective reflection, the reflection wavelength being in an infrared wavelength region, and the reflection film exhibiting a direct transmittance of non-polarized visible light of 50% or more and a haze value of 5% or less; and an optical member including the reflection film, which can be used as a handwriting input sheet. The optical member can be used by being stuck to the surface of a display.
