| abstract | A polyimide precursor containing a repeating unit represented by the formula (1) and having a polymerization degree of 0.05 to 5.0 dl / g (concentration 0.5 g / dl in N-methylpyrrolidone at a temperature of 30 ° C.) in terms of reduced viscosity; It contains the repeating unit represented by (2), The polymerization degree contains the solvent-soluble polyimide resin of 0.05-5.0 dl / g (concentration 0.5g / dl in N-methylpyrrolidone of temperature 30 degreeC) in conversion viscosity. Moreover, 1-80 weight% of solvent-soluble polyimides represented by General formula (2) are contained with respect to the total polymer weight, The liquid-crystal aligning agent characterized by the above-mentioned.n n n n n n n n n n n n n (Wherein R 1 and R 3 are tetravalent organic groups constituting tetracarboxylic acid and derivatives thereof, R 2 represents a divalent organic group constituting diamine, and R 4 is a fluorine-containing alkyl group or a C6 or more long-chain alkyl group) It represents the divalent organic group which comprises the diamine which does not have, and m and n are positive integers.) |
