摘要： The present invention provides a method of producing simply and precisely an anisotropic optical element having optical properties that are anisotropic with respect to a direction of a normal to an element plane. After forming an uncured film by applying flatwise a radiation-polymerizable cholesteric liquid crystal to a substrate (step 101), the film is heated to convert the cholesteric phase of the liquid crystal in the film into an isotropic phase (step 102). Thereafter, the isotropic phase of the liquid crystal in the film is converted into the cholesteric phase thereof, with a gas blown on the film from a predetermined direction (step 103). By doing so, the liquid crystal is oriented in such a manner that a mean direction of directions of helical axes (a main direction of helical axes) in liquid crystal domains in the film is tilted, relative to a direction of a normal to a film plane, along a stream of the gas blown. Lastly, the liquid crystal in the film is polymerized with the phase of the liquid crystal in the film maintained cholesteric (step 104). By this, the above-described state of orientation of the liquid crystal in the film is fixed as it is, and there is produced an anisotropic optical element having optical properties that are anisotropic with respect to the direction of the normal to the element plane.

This is achievable as follows. A volume hologram layer is formed on a substrate, and a cholesteric liquid crystal layer is then formed on another substrate comprising a center substrate film that is subjected to bondable treatment. The volume hologram layer is applied to the center substrate film that is subjected to bondable treatment, and placed in a state where the volume hologram layer and cholesteric liquid crystal layer are laminated together via the substrate. The substrate is peeled off the volume hologram layer, and an adhesive layer is formed on the surface of the volume hologram layer off which the substrate is peeled off, followed by the provision of the substrate on the adhesive layer. Finally, the multilayer structure is shaped into a label form of cholesteric liquid crystal medium having a volume hologram layer.

The polarized-light selective reflection layer includes three partial selective reflection layers, each of which contains molecules of a liquid crystal made from an organic compound, forming an organic film as a whole, and has a cholesteric liquid crystalline structure that causes selective diffuse-reflection of a specific polarized-light component. Each partial selective reflection layer of the polarized-light selective reflection layer is ordered according to wavelength of the range of light reflected. Beginning from the observation side, the order is as follows: blue (B) color wave range, green (G) color wave range, and red (R) color wave range.

摘要： A radiation-curing liquid crystal having cholesteric regularity is applied to a glass substrate 11 provided with an alignment layer 12 to form a first cholesteric liquid crystal film 13 in the uncured state (FIG. 2(a)). Radiation 20 is then selectively applied, through a photomask 14, to the desired portions of the first cholesteric liquid crystal film 13 to partially cure it (FIG. 2(b)); thereafter, the first cholesteric liquid crystal film 13 is immersed in an organic solvent 22 to remove the uncured portions 13b thereof (FIG. 2(c)), thereby forming the first cholesteric liquid crystal film 13 in a desired pattern (FIG. 2(d)). Then, in the same manner as described above, a radiation-curing liquid crystal having cholesteric regularity is applied to the surface of the formed first cholesteric liquid crystal film 13 and the alignment layer 12 to form a second cholesteric liquid crystal film 13′ in the uncured state (FIG. 2(e)). To the second cholesteric liquid crystal film 13′, application of radiation 20 (FIG. 2(f)) and immersion in an organic solvent 22 (FIG. 2(g)) are carried out to remove the uncured portions 13b′ thereof (FIG. 2(e)), thereby producing an optical element 10 having the cholesteric liquid crystal films 13 and 13′ in desired patterns (FIG. 2(h)).

摘要： A projection screen includes a polarized-light selective reflection layer having a cholesteric liquid crystalline structure, capable of selectively diffuse-reflecting a specific polarized-light component; a substrate for supporting the polarized-light selective reflection layer; and an optical member provided on the observation side of the polarized-light selective reflection layer. The optical member diffuses imaging light which the polarized-light selective reflection layer diffuse-reflects, while maintaining the state of polarization of the imaging light. The optical member diffuses right-handed circularly polarized light that is projected on the projection screen, when the light travels from the observation side to the polarized-light selective reflection layer. The diffused light (31a1) enters the polarized-light selective reflection layer and is diffuse-reflected owing to the scattering property of the polarized-light selective reflection layer (the property of diffusing light that is selectively reflected, owing to structural non-uniformity in the cholesteric liquid crystalline structure containing a plurality of helical structure parts, the helical axes of which extend in different directions). The optical member further diffuses this diffused light (31a2) when the light travels from the polarized-light selective reflection layer toward the observation side. The thus diffused light (31a3) finally emerges toward the observation side.
