Provided is a liquid crystal aligning agent which provides a liquid crystal display device having little unevenness in the display around a sealant while exhibiting high reliability. The liquid crystal aligning agent comprises a compound (A) having a partial structure represented by chemical formula (1). In chemical formula (1), R_1 is a protecting group of an amino group, and two *1 represent bonding hands which are bound to a hydrocarbon group. (과제) 높은 신뢰성을 나타내면서, 시일제 주변의 표시 불균일이 적은 액정 표시 소자를 얻을 수 있는 액정 배향제를 제공한다. (해결 수단) 하기식 (1)로 나타나는 부분 구조를 갖는 화합물 (A)를 액정 배향제에 함유시킨다:(식 (1) 중, R은 아미노기의 보호기이고; 2개의 「*1」은, 탄화수소기에 결합하는 결합손인 것을 나타냄).
