Cholesteric liquid crystal layer, laminate, optical anisotropic body, reflective film, manufacturing method of cholesteric liquid crystal layer, counterfeit preventing medium, and judgment method

摘要

Problem to be solved: to provide a cholesteric liquid crystal layer having excellent reflection anisotropy and low haze and high in circular polarization of reflected light, and a method of manufacturing the same.A laminate including an cholesteric liquid crystal layer, an optical anisotropy and a reflecting film are provided.It is a cholesteric liquid crystal layer formed using liquid crystal compound.At least one major surface of the pair of principal surfaces of the cholesteric liquid crystal layerThe direction of the molecular axis of the liquid crystal compound changes continuously while rotating continuously in at least one direction in the planeMolecular axis of liquid crystal compoundInclined to the main surface of the cholesteric liquid crystal layerIn the cross section perpendicular to the main surface, the alignment direction of the bright and dark portions of the cholesteric liquid crystal phase observed by the scanning electron microscope isInclined to the main surface of the cholesteric liquid crystal layerCholesteric liquid crystal layer.
