Zusammenfassung:	This liquid crystal alignment agent comprises: a polyimide soluble in a solvent and using a diamine compound represented by formula (1) in at least a portion of the material thereof; a polyamic acid; and a solvent. (In formula (1), X1 is an oxygen atom or a sulfur atom, Y1 is a single bond, -O-, -S-, or -COO-* (wherein the bonding hand with the "*" bonds with R1), and R1 is a C1-3 alkylene group.)
