Title:
COMPOSITION FOR FORMING RADICAL-GENERATING FILM, RADICAL-GENERATING FILM, METHOD FOR PRODUCING LIQUID CRYSTAL DISPLAY ELEMENT, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/092088
Kind Code:
A1
Abstract:
Provided is a composition for forming a radical-generating film, which contains: a component (A), a polymer used as an alignment component of a liquid crystal aligning agent for in-plane switching; and a component (B), a polymer which contains a group represented by formula (1) and which has a structural unit derived from a monomer having a polymerizable carbon-carbon unsaturated bond. (In formula (1), * denotes a bonding position, and R1 denotes a single bond, -CH2-, -O-, -COO-, -OCO-, -NHCO-, -CONH-, -NH-, -CH2O-, -N(CH3)-, -CON(CH3)-, or -N(CH3)CO-. R2 denotes a single bond or a C1-20 alkylene group which is unsubstituted or substituted with a fluorine atom. One or more arbitrary -CH2- or -CF2- moieties in the alkylene group may each independently be substituted with a group selected from among -CH=CH-, an optionally substituted divalent carbon ring and an optionally substituted divalent heterocyclic ring. Furthermore, one or more arbitrary -CH2- or -CF2- moieties in the alkylene group may be substituted with the groups listed below, that is, may be substituted with at least one of -O-, -COO-, -OCO-, -NHCO-, -CONH- or -NH- as long as these are not adjacent to each other. R3 denotes an organic group that induces radical polymerization.)
