    Abstract: The present invention provides a viewing system capable of providing varying visual effects with a simpler configuration. In addition, the present invention also provides a display device, a stage installation, and a polymerizable liquid crystal composition. A viewing system according to the present invention is a viewing system for viewing an object to be irradiated including a light source unit, and the object to be irradiated with light emitted from the light source unit, in which the object to be irradiated includes a member, and a first circularly polarized light reflecting layer that is arranged on the member and reflects either right-handed circularly polarized light or left-handed circularly polarized light, the light source unit is capable of emitting light to be switchable between either right-handed circularly polarized light or left-handed circularly polarized light that is reflected by the first circularly polarized light reflecting layer or natural light, and circularly polarized light having a revolution direction opposite to a revolution direction of the circularly polarized light reflected by the first circularly polarized light reflecting layer, and color of the object to be irradiated is changed by switching light emitted from the light source unit.

    Abstract: 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.
