Title:
LIQUID CRYSTAL COMPOSITION FOR LIGHT CONTROL, AND LIGHT CONTROLLING FILM
Document Type and Number:
Japanese Patent JP2022119743
Kind Code:
A
Abstract:
To provide means capable of compatibly obtaining high transparency in a transparent state and a high reflection factor in a non-transparent state in a light controlling film with an optical state thereof changeable between the transparent state and non-transparent state.SOLUTION: A liquid crystal composition for light control includes: liquid crystal molecules; an optical active material including a photoisomerized material; a photopolymerizable monomer; and nano particles. Based on 100 mass pts. of the liquid crystal molecules, a content of the photopolymerizable monomer is 4.5 to 10.0 mass pts., a content of the nanoparticles is more than 0 and equal to or less than 1.4 mass pts., and a ratio of the nanoparticles to the total mass of the photopolymerizable monomer and the nanoparticles is 1 to 15 mass%.SELECTED DRAWING: None
