LIQUID CRYSTAL ALIGNING AGENT, METHOD FOR FORMING LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a liquid crystal aligning agent containing a radiation-sensitive polysiloxane which is obtained by reacting at least one substance selected from the group consisting of polysiloxanes having a repeating unit represented by Formula (1), hydrolysis products thereof and condensates of the hydrolysis products, with a cinnamic acid derivative having at least one group selected from the group consisting of alkenyl groups and alkynyl groups. (1) (In Formula (1), Y1 represents a hydroxy group, an alkoxyl group having 1-10 carbon atoms, an alkyl group having 1-20 carbon atoms or an aryl group having 6-20 carbon atoms.)
