Production of oriented film for liquid crystal

摘要: PURPOSE:To form the stable film for orientation of liquid crystal molecules in a stage dissolving main chain type polymer solvent and applying soln. on substrate by uniform stresses this at time application further, evaporating solvent. CONSTITUTION:The are applied to substrate. The uniformly spread over entire surface oriented when thereon application. low-molecular an interaction come these molecules. Such generated immersing pulling up one direction or blade method printing lithography intaglio printing. diluted formed thickened as evaporates until attain state approximate state. process processing which does not produce dust, has good controllability is low cost obtd. way.
