Provided is a liquid crystal alignment agent capable of forming a liquid crystal alignment film having a rare decease in a voltage maintenance rate for a long time and excellent reliability. The present invention relates to a liquid crystal alignment agent containing a polymer having a structure represented by Formula (1): (1) (In Formula (1), X^1 and X^2 are single bonds, oxygen atoms, sulfur atoms, carbonyl groups, or ester bonds. X^1 and X^2 are not single bonds at the same time. Y is a group obtained by removing two hydrogen atoms from a 5-ringed or 6-ringed hetero-aromatic compound including one or two hetero atoms selected from the group consisting of a nitrogen atom, an oxygen atom, and a sulfur atom in a ring structure. Two coupling hands of Y directly cats from a 5-ring or 6-ring. A plurality of R^1 are a hydrogen atom or a fluorine atom. m1 and m2 are integers of 0-20, and ′*′ respectively represents coupling hands.)
