The liquid crystal aligning film which has favorable liquid-crystal orientation can be obtained, and the liquid crystal aligning agent with which the sensitivity margin increased is provided. At least 1 selected from the group consisting of a polyamic acid obtained by reaction of a diamine component containing diamine having a structure represented by the following formula [1] and a tetracarboxylic dianhydride component, and a polyimide obtained by imidizing the polyamic acid The liquid crystal aligning agent containing the polymer of dog. (In formula [1], A 1 and A 2 are each independently a monocyclic group or a condensed cyclic group which may have a substituent, and A 1 and A 2 are not at the same time a monocyclic group. X 1 and X 2 are each independently a single bond, an oxygen atom, or a sulfur atom. Q is an alkylene group having 1 or 2 carbon atoms. m and n are each independently an integer of 1 to 3.) |
