Patent ID: 8304031

Claim:
A method of forming a liquid crystal alignment film, the method comprising: applying a liquid crystal aligning agent to a substrate, thereby forming a coating film, and applying radiation to the coating film, wherein the liquid crystal aligning agent comprises a radiation sensitive polyorganosiloxane which is obtained by reacting at least one component selected from the group consisting of a polyorganosiloxane having a recurring unit represented by the following formula (1), a hydrolysate thereof and a condensate of the hydrolysate with a cinnamic acid derivative having at least one group selected from the group consisting of a carboxyl group, a hydroxyl group, —SH, —NCO, —NHR, wherein R is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and —SO 2 Cl: wherein X 1 is a monovalent organic group having an epoxy group, and Y 1 is a hydroxyl group, an alkoxyl group having 1 to 10 carbon atoms, an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms, and wherein when the applied radiation is linearly polarized or partially polarized, the radiation is applied in a direction perpendicular to the surface of the substrate, an oblique direction, or both directions, and wherein when the applied radiation is non-polarized radiation, the radiation is applied in an oblique direction.
