Title:
OPTICAL ANISOTROPIC LAYER AND MANUFACTURING METHOD THEREFOR, OPTICAL ANISOTROPIC LAMINATE, AND CIRCULARLY POLARIZING PLATE
Document Type and Number:
WIPO Patent Application WO/2017/110631
Kind Code:
A1
Abstract:
An optical anisotropic layer obtained by curing a liquid crystal composition containing a photopolymerizable liquid crystal compound, wherein the ratio of the photopolymerizable liquid crystal compound in the optical anisotropic layer is 25 wt% or less, and the absorbance of the optical anisotropic layer satisfies a predetermined relationship at a maximum absorption wavelength with respect to polarized light parallel to the alignment direction of the optical anisotropic layer and at a maximum absorption wavelength with respect to polarized light perpendicular to the alignment direction of the optical anisotropic layer in a first wavelength range of 230 nm or more and less than 300 nm, and in a second wavelength range of 300-400 nm, respectively.
