To provide a polyimide precursor and/or polyimide which has an excellent solubility in various organic solvents, and with which a liquid crystal alignment film can be obtained which is excellent in a rubbing resistance and which is hardly deteriorated even by irradiation with backlight. n A polyimide precursor having its terminal amino group modified with at least one alicyclic epoxydicarboxylic acid anhydride selected from the group consisting of compounds of the formulae [1] and [2], or a polyimide obtained by imidizing it: n nwherein Y is a C 1-2 alkylene or an oxygen atom, and R 1 is a hydrogen atom or an organic group represented by —X 1 —X 2 —X 3 , wherein X 1 is a single bond or —CH 2 —, X 2 is a single bond or —O—, and X 3 is a C 1-20 alkyl group, a C 1-20 haloalkyl group or a C 1-20 alkyl group containing a cyano group. |
