Title:
METHOD FOR PRODUCING CHOLESTERIC LIQUID CRYSTAL LAYER
Document Type and Number:
WIPO Patent Application WO/2021/131441
Kind Code:
A1
Abstract:
The present disclosure provides a method for producing a cholesteric liquid crystal layer, said method comprising: a step for applying a composition to a base material, said composition containing a liquid crystalline compound and a chiral agent, the helical twisting power of which is changed by light irradiation; a step for applying a shear force to the surface of the composition applied to the base material; and a step for irradiating the composition, to which the shear force has been applied, with ultraviolet light that includes a wavelength that changes the helical twisting power of the chiral agent, the helical twisting power of which is changed by light irradiation.
