    Abstract: An optical member and an image display device including an optical member having a support, an underlayer, and a wavelength selective reflection portion in this order, in which the wavelength selective reflection portion has wavelength selective reflecting properties, the wavelength selective reflection portion has a cholesteric structure which has a stripe pattern including bright portions and dark portions in a cross-sectional view of the wavelength selective reflection portion when observed with a scanning electron microscope, the underlayer absorbs invisible light, and a wavelength range where the wavelength selective reflection portion has wavelength selective reflecting properties overlaps a wavelength range of invisible light absorbed by the underlayer. In the optical member, a Signal/Noise ratio is high which is a ratio of a reflectance of the wavelength selective reflection portion to a reflectance of the underlayer in a wavelength range where the wavelength selective reflection portion has wavelength selective reflecting properties.

    Abstract: A polarized light irradiation device of the present disclosure has: a light source unit which continuously emits polarized light; a light shaping unit which shapes the polarized light emitted from the light source unit into a preset shape to irradiate an irradiation target object with the shaped polarized light; a transport mechanism which transports the irradiation target object relative to the light source unit; and an interlocking mechanism which periodically and continuously changes a direction of linearly polarized light applied to the irradiation target object or an azimuthal angle of elliptically polarized light applied to the irradiation target object according to an amount of transport of the irradiation target object relative to the light source unit by the transport mechanism.

    Abstract: A laminate has a first polarizer, a first patterned optical anisotropic layer, a second patterned optical anisotropic layer, and a second polarizer, in which an angle formed between transmission axes of the polarizers is 90°+5°; each of the patterned optical anisotropic layers has three or more phase difference regions, which have different slow axis directions and in which the slow axis directions continuously change, in a plane of each of the first patterned optical anisotropic layer and the second patterned optical anisotropic layer; a transmission display state and a light-blocking display state are switched with each other by changing an angle formed between the slow axis direction of each of the phase difference regions of the first patterned optical anisotropic layer and the slow axis direction of each of the phase difference regions of the second patterned optical anisotropic layer that is superposed on each of the phase difference regions of the first patterned optical anisotropic layer; a combination of the patterned optical anisotropic layers is a combination of a +A plate and −A plate; and at least one of the polarizers is a reflective-type polarizer.

    Abstract: Provided are a transparent film that allows scenery to be observed without color unevenness in a state where light is not irradiated, a transparent screen and an image display system including the transparent film, and a transparent poster. The transparent film includes: a support; a dot array that is formed on one surface of the support and in which dots obtained by immobilizing a cholesteric liquid crystalline phase are two-dimensionally arranged; and an overcoat layer that covers the dots and is laminated on the support, in which areas of the dots and distances between the dots are made to be irregular. As a result, the object is achieved.
