Abstract
A thin film forming chemical absorption material including at least a functional group of the formula CF —CF —CH —O—(benzene)—CH=CH—C(O)—(benzene)— and a —SiX group (X represents halogen) as an end group bonded by siloxane bond. The chemical absorption material can form a monomolecular thin-film having photosensitive groups that are transparent and stable in a visible light region and cause photochemical reaction in an ultraviolet region. A liquid crystal alignment film includes an aggregation of adsorption molecules chemically absorbed directly on a surface with electrodes or chemically adsorbed indirectly thereon through another material layer having a characteristic group the formula above and a —O—Si bond group at a molecular end group. The liquid crystal alignment film is uniformly and strongly anchored on the substrate, has excellent thermal alignment stability, alignment controllability, and a film thickness permitting formation with good productivity.
