摘要
Methods for forming an orientation film comprising a first step wherein a silane coupling agent is chemically adsorbed on a substrate surface, and a second step wherein an organic compound comprising a functional group capable of coupling with the silane coupling agent is coupled with the silane coupling agent. The second step includes a) applying a magnetic or electrical field in a selected direction to a mixture of 1) a liquid crystal compound being in a liquid crystal phase when heated and 2) the organic compound, b) contacting the substrate with the mixture which is in the applied magnetic or electrical field, and c) heating the mixture which is contacted with the substrate to a temperature sufficient for coupling of the silane coupling agent and the organic compound during the magnetic or electrical field application. The organic compound coupled with the silane coupling agent is directed toward a direction corresponding to the selected direction of the magnetic or electrical field.
