Abstract: A thin film forming chemical absorption material including at least a functional group of the formula CF3—CF2—CH2—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.

Abstract: A novel chemical adsorbate compound capable of forming a monomolecular thin film is provided. The chemical adsorbate compound is transparent and stable in the visible light range, and has a photosensitive group which causes a photochemical reaction in the ultraviolet light range. Utilizing the chemical adsorbate compound, a liquid crystal alignment film is also provided. The liquid crystal alignment film has an excellent thermal stability and alignment control performance. Utilizing liquid crystal alignment film, a liquid crystal display device is further provided. The liquid crystal display device achieves wide viewing angles and clear display images at small driving voltages. These are achieved by, as one example, providing a chemical adsorbate compound including a chalcone derivative having a COO group at the 4′ position in the chalcone skeleton and an —SiX3 group, where X is a halogen, at the molecular end adjacent to the COO group.
