Title:
COMPOSITION FOR FORMING POLARIZATION FILM
Document Type and Number:
WIPO Patent Application WO/2019/151228
Kind Code:
A1
Abstract:
This composition for forming a polarization film comprises: a polymerizable liquid crystal compound; a dichroic dye; a photopolymerization initiator; and an organic solvent. The composition for forming a polarization film satisfies formula (1): A (380) ≥ 1.2 [In the formula, A (380) represents the absorbance (at 380 nm) of a solution obtained by diluting the composition for forming a polarization film with the organic solvent to a concentration of 0.4% by mass.]
