PROCESS FOR THE PRODUCTION OF MONOMOLECULAR CHEMISORPTION FILM AND PROCESSES FOR THE PRODUCTION OF LIQUID CRYSTAL ALIGNMENT FILMS AND LIQUID CRYSTAL DISPLAYS BY USING THE CHEMISORPTION FILM

摘要

Uniformity and molecular orientation, so that a chemically adsorbed monomolecular layer that can be used as a liquid crystal alignment layer can be efficiently produced.;The object of the present invention is achieved by a process for producing an aqueous solution, comprising the steps of bringing an adsorbate solution containing a silane-based surfactant and a non-aqueous (non-aqueous) organic solvent into contact with a substrate surface in a dry atmosphere, A condensation accelerating step of carrying out a chemical adsorption reaction while evaporating the organic solvent contained in the layer, an aging reaction step of continuing the chemical reaction until a predetermined time elapses after the evaporation of the organic solvent is completed, And a cleaning step of cleaning the non-adsorbed surfactant remaining on the surface of the substrate by using a non-aqueous organic solvent after the reaction step is minimized.
