    摘要: A sheet with anti-counterfeit functions for making counterfeiting highly difficult in the case where authentication information is recorded using the properties of cholesteric liquid crystal is provided. A cholesteric liquid crystal layer 110 having a selective reflected wavelength band in at least the visible light region is provided in such a manner that this cholesteric liquid crystal layer 110 is a single layer of which thickness is approximately uniform, and an authentication region 112 of which selective reflected wavelength band is different is provided in at least one place. Preferably, an adhesive layer 130 is provided on one side of the cholesteric liquid crystal layer 110. Preferably, a base 120 is provided between the cholesteric liquid crystal layer 110 and the adhesive layer 130. Preferably, a light absorbing layer 140 is provided on adhesive layer 130 of the cholesteric liquid crystal layer 110.

    摘要: An optical element of the invention comprises at least three laminated circular-polarization-type-reflection polarizers (a) whose wavelength bands for selective reflection of polarized light overlap one another; a layer (b1) which is placed between at least a pair of the circular-polarization-type-reflection polarizers (a) and has a front retardation of substantially zero (in the normal direction) and a retardation of at least λ/8 with respect to incident light inclined by at least 30° relative to the normal direction; and a layer (b2) which is placed between at least another pair of the circular-polarization-type-reflection polarizers (a) and has a front retardation of substantially zero (in the normal direction) and a retardation of at most λ/2 with respect to incident light inclined by 60° relative to the normal direction. The optical element condenses or collimates incident light from a light source and can control transmission of light at large incident angles relative to the normal direction, increase front brightness and reduce coloration.
