A liquid crystal aligning agent is provided to form no foam when applied onto a substrate, to ensure good coatability, and to produce liquid crystal aligning films having good liquid crystal aligning properties and electric characteristics. A liquid crystal aligning agent contains (A) a polymer having a repeat unit represented by the following formula 1a and/or a repeat unit represented by the following formula 1b, and (B) an epoxy compound represented by the following formula 2. In the formula 1a, P^1 is a tetravalent organic group and Q^1 is a divalent organic group. In the formula 1b, P^2 is a tetravalent organic group and Q^2 is a divalent organic group. In the formula 2, n is an integer of 1-30 and R1 is an n-valent organic group.
