Radical-generating film-forming composition, radical-generating film, method for manufacturing liquid crystal display element, and liquid crystal display element

A radical-generating film-forming composition containing the following components: component (A): a polymer that serves as an alignment component of a liquid crystal alignment agent for transverse electric field driving, and component (B): a polymer that contains a group represented by formula (1) and has a structural unit derived from a monomer having a polymerizable carbon-carbon unsaturated bond: *-R1R2-R3 (1) (in formula (1), * represents a bonding site; (In the formula, R1 represents a single bond,-CH2-,-O-,-COO-,-OCO-,-NHCO-,-CONH-,-NH-,-CH2O-,-N (CH3)-,-CONN (CH3)-, or-N (CH3) CO-. R2 represents a single bond, or an unsubstituted or fluorine-substituted alkylene group having 1-20 carbon atoms, one or more of-CH2-or-CF2-in the alkylene group may be independently substituted by a group selected from the group consisting of-CH = CH-, a divalent carbocyclic ring optionally having a substituent, and a divalent heterocyclic ring optionally having a substituent, and further, R2 represents a hydrogen atom or a
