Abstract
PURPOSE: To obtain a liquid crystal display panel of stable horizontal orientation performance with simple equipment and operations by using plastic panels and forming orientation treatment films with polyimide having specific repeating units.
CONSTITUTION: The polymer of the formula III of which repeating units are expressed by the formula I or formula II or the polymer formed by reacting bismaleimide and benzyloxime is dissolved in a suitable solvent and is coated on panel substrates of plastic films provided with transparent conductive films of indium oxide or the like. After this is dried, it is baked at ≤150°C, whereby the orientation treatment films of 0.1μWseveral 1,000Åthickness are formed. Thence, they are subjected to rubbing treatment. The liquid crystal display panel having sufficient performances for practical use is obtained by this method.
