description	Provided are a liquid crystal alignment agent which makes it possible to obtain a liquid crystal alignment film which has excellent voltage holding ratio, rapid relaxation of accumulated charges, and satisfactory liquid crystal alignment property and transparency, a liquid crystal aligned film, and a liquid crystal display device. The liquid crystal alignment agent includes the following component (A), component (B), and an organic solvent. The component (A) is a polymer of at least one type selected from the group consisting of a polyimide precursor, an imidized polymer of the polyimide precursor, and a photosensitive branched acrylic polymer that exhibits liquid crystallinity in a temperature range of 100°C-300°C. The component (B) is a compound represented by the following formula (1) (Q1, Q2 are each (Q1-1) or the like; either Q1 or Q2 is (Q1-1)) (q1, q2 is 0 or 1; R1 is a hydrogen atom or the like, R2, R3 are each a group having an epoxy moiety, or the like, either R2 or R3 is a group having an epoxy moi
