<p>The present invention, which enables alignment of liquid crystal molecules when no voltage is applied thereto and also enables control of the pretilt angle of the liquid crystal molecules, relates to a composition for liquid crystal alignment films, and the like, said composition containing the components (A)-(D) described below. (A) A meta-phenylenediamine derivative represented by general formula (1) (B) A meta-phenylenediamine derivative represented by general formula (2) (C) A para-arylenediamine represented by general formula (3) (D) A tetracarboxylic acid represented by general formula (4) or a tetracarboxylic acid anhydride represented by general formula (4') (In the formulae, R1 represents an alkyl group having 1-6 carbon atoms, or the like; R2 represents an alkyl group having 8-20 carbon atoms, or the like; each of t-number Ra moieties represents an alkyl group having 1-3 carbon atoms, or the like; n represents an integer of 1-3; t represents an integer of 0-4; T represents an oxygen atom or the like; Y represents an amino group; and Z represents a tetravalent hydrocarbon group.)</p> |
