PROBLEM TO BE SOLVED: To provide a liquid crystal aligning agent capable of forming an optical alignment layer enhanced in the optical stability of a voltage holding ratio of a liquid crystal display element, to provide a liquid crystal alignment layer formed by using the liquid crystal aligning agent, and to provide the liquid crystal display element using the liquid crystal alignment layer. SOLUTION: The liquid crystal alignment layer is formed of the liquid crystal aligning agent containing a polyamic acid or its derivative obtained by making a tetracarboxylic dianhydride represented by a formula (G) react with cinnamate-based diamine, and is used for the liquid crystal display element.
