A liquid crystal alignment treatment agent comprising the following components (A) and (B). Component (A): Propylene glycol monobutyl ether. Component (B): At least one polymer selected from a polyimide precursor or polyimide obtained by reacting a diamine component having a structure represented by the following formula [1] with a tetracarboxylic acid component. (Wherein, Y 1 represents a single bond, Y 2 represents a single bond or - (CH 2 ) b - (b is an integer of 1 to 15), Y 3 represents a single bond or the like , Y 4 represents a bivalent cyclic group, Y 5 represents a bivalent cyclic group, n represents an integer of 0 to 4, and Y 6 represents an alkyl group having 1 to 18 carbon atoms. |
