LIQUID CRYSTAL ALIGNING AGENT LIQUID CRYSTAL ALIGNING FILM PROCESS FOR FORMING THE LIQUID CRYSTAL ALIGNING FILM LIQUID CRYSTAL DISPLAY DEVICE AND RADIATION-SENSITIVE POLYORGANOSILOXANE

摘要

The present invention provides a liquid crystal aligning agent capable of imparting a pretilt angle by a photo alignment method and providing a liquid crystal alignment film excellent in stability over time of a given pretilt angle.;Wherein the liquid crystal aligning agent is selected from the group consisting of a specific polyorganosiloxane having an epoxy group and (A) a cinnamic acid derivative, and (B) an acetophenone structure, a benzophenone structure, an anthraquinone structure, a biphenyl structure, a carbazole structure, A radiation-sensitive polyorganosiloxane obtained by reacting a specific compound having a photosensitizing structure selected from the group consisting of a fluorene structure, a fluorene structure, a naphthalene structure, an anthracene structure, an acridine structure and an indole structure.;A liquid crystal aligning agent, a liquid crystal alignment film, a liquid crystal display element, a radiation sensitive polyorganosiloxane
