An object of the present invention is to provide a liquid crystal aligning agent that is excellent in storage stability and can form a liquid crystal aligning film with good reworkability and good liquid crystal alignment. The liquid crystal aligning agent comprises (A) component, (B) component, and (C) component. (A) is a polymer; (B) is a compound (where the (A) component is excluded) having two or more nucleophilic functional groups or acidic functional groups in one molecule and one or more of the nucleophilic functional groups or acidic functional groups present in one molecule having a partial structure [T] in which a nitrogen atom, a sulfur atom, or an oxygen atom is bonded to a releasable group that is releasable by at least one of heat and light; and (C) is a compound (where the (A) component and a compound having a radically polymerizable carbon-carbon double bond are excluded) having two or more electrophilic functional groups in one molecule. (과제) 보존 안정성이 우수하고, 리워크성 및 액정 배향성이 양호한 액정 배향막을 형성할 수 있는 액정 배향제를 제공하는 것. (해결 수단) (A) 성분, (B) 성분 및 (C) 성분을 함유하는, 액정 배향제. (A) 중합체; (B) 구핵성 관능기 또는 산성 관능기를 1분자 내에 2개 이상 갖고, 또한 1분자 내에 존재하는 구핵성 관능기 또는 산성 관능기 중 1개 이상이, 질소 원자, 황 원자 또는 산소 원자와, 열 및 빛 중 적어도 한쪽에 의해 탈리하는 탈리성기가 결합한 부분 구조 [T]를 갖는 화합물(단, 상기 (A) 성분을 제외함); (C) 구전자성 관능기를 1분자 내에 2개 이상 갖는 화합물(단, 상기 (A) 성분 및 라디칼 중합성의 탄소-탄소 이중 결합을 갖는 화합물을 제외함)
