<p>PURPOSE:To obtain a liquid crystal display element providing picture image of high quality by intercalating liquid crystal into a pair of substrate comprising transparent electrodes and orientation films covering the electrodes wherein the orientation films are formed by forming film developed by an arom. org. compd. expressed by the general formula: X.Y.Z (where X is a hydrophobic group; Y is a group having pi-electron system; and Z is a hydrophilic group) on water surface, then adhering the at least one layer of the org. compd. in such a manner that the pi-electron system comes to the outermost surface of the layer. CONSTITUTION:Nesa patterns 2, 2' having a specified shape which serve as transparent electrode are formed on a substrate 1, 1' such as glass, plastic, etc., and liquid crystal orientation film 4, 4' are adhered to the whole surface including the transparent electrode, and the periphery is surrounded by a sealing agent 3, 3' and the liquid crystal 5 is poured therein. In this constitution, a soln. prepd. by dissolving 15-phenyl pentadecanoic acid expressed by the formula (I) in benzene is used as the orientation film 4, 4', by developing (I) by dropping on water surface 8 and compressing with a float 7 together with a weight 6 to form the film 9. In this case, the film 9 is constituted of a hydrophilic group, hydrophobic group, and a group having pi-electron system arranging the pi-electron system group to be exposed to the surface. Thus, the extent of insufficient orientation is reduced.</p> |
