摘要 |
The present invention provides the following: a photo alignment method-use liquid crystal aligning agent used to obtain a photo alignment method-use liquid crystal alignment film that does not cause bright spots even when negative liquid crystals are used, and that is capable of achieving good after-image characteristics; a liquid crystal alignment film obtained from the liquid crystal aligning agent; and a liquid crystal display element provided with the liquid crystal aligning agent. Provided is the liquid crystal aligning agent which contains a polyimide or polyimide precursor obtained from a reaction between: a tetracarboxylic acid dianhydride represented by formula (1) (in the formula, X1 is as set forth in the present specification) or a derivative thereof; and a diamine component that contains a diamine represented by formula (2) (in the formula, R1, Z1 and n are as set forth in the present specification). |
