    • 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 ―SiX 3 group, where X is a halogen, at the molecular end adjacent to the COO group. Another example of the chemical adsorbate compound is a compound in which a linear hydrocarbon group is ether-linked at the 4 position of the benzene ring in the chalcone skeleton and an ―SiX 3 group, where X is a halogen, is ether-linked to the hydrocarbon group.
