摘要
PURPOSE: To provide a composition for a liquid crystal oriented film by which a pretilt angle becomes 5 or more without creating a domain when a liquid crystal display element is manufactured and the pretilt angle is not changed by aging after liquid crystal is sealed. ;CONSTITUTION: A composition for a liquid crystal oriented film contains (1) aromatic diamine expressed by a formula (R represents a bivalent condensed ring hydrocarbon radical having the carbon number of 12 to 22, and the condensed ring hydrocarbon radical may be substituted with an alkyl group), (2) aromatic diamine having a hexafluoro isopropylidene, (3) tetra carboxylic acid dianhydride and (4) polyamide acid obtained by reacting diamine except (1) and (2) according to its necessity, and the liquid crystal oriented film and the like are formed by using this composition.;COPYRIGHT: (C)1994,JPO
