Disclosed is a liquid crystal alignment agent which includes: a polymer obtained by subjecting a diamine compound and a tetracarboxylic dianhydride compound to a polymerization reaction; an epoxy group containing compound; and a curing promoter. The curing promoter is at least one compound selected from secondary amines, tertiary amines, quaternary ammonium compounds, organic phosphines, imidazoles, and tetraphenyl borates, and is in an amount ranging from 0.5 to 10 parts by weight based on 100 parts by weight of the polymer. A liquid crystal alignment film formed from the liquid crystal alignment agent and a liquid crystal display element including the liquid crystal alignment film are also disclosed. |
