This invention is too provide a bisaniline derivative having no oxygen atom or sulfur atom in the molecule, and represented by general formula (1), and further to provide a polyamic acid, a polyamide or a polyamide obtained by using the derivative as a raw material, or an oriented film for liquid crystal display, obtained by using the polyamic acid or the polyamide. This bisaniline derivative is represented by general formula (1) (where A is a 2-50C straight-chain or branched divalent group; n is an integer of 2-4; X1, X2, X3, X4, X5, X6, X7 and X8 are each independently a hydrogen atom, a methyl group or a fluorine atom). |
