    Abstract: The present invention provides an illuminating device that makes it possible to reduce the number of members for regulating a polarization state and can irradiate light having natural color shades without decreasing energy efficiency of light irradiation, and a plant growth regulation method using the illuminating device. The illuminating device of the present invention includes a light-emitting light source and a polarization state regulation member that regulates a polarization state of the light-emitting light source, in which the polarization state of a wavelength region of a portion of emission wavelengths is changed to circular polarization, and a degree of circular polarization of light in a wavelength band for regulation among the light rays to be irradiated is 0.3 or higher. In a preferable embodiment, a width of at least one wavelength band for regulation of the polarization state regulation member is from 60 nm to 250 nm.

    Abstract: 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.

    Abstract: A circularly polarizing plate includes a polarizing film, a first optically anisotropic layer, and a second optically anisotropic layer in this order, in which the first optically anisotropic layer contains a twisted aligned liquid crystal compound of which a helical axis is a thickness direction thereof, a helix angle of the liquid crystal compound is 28.6±10°, an absorption axis of the polarizing film and an in-plane slow axis of the second optically anisotropic layer are parallel or orthogonal to each other, Δnd and ReB(550) respectively fall in predetermined value ranges. The circularly polarizing plate can sufficiently suppress the mixing of black with other colors in a front direction when being stuck on a display apparatus. A retardation plate used for the circularly polarizing plate and an organic EL display apparatus that have the circularly polarizing plate are also provided.
