A liquid crystal alignment treating agent for vertical alignment with which a liquid crystal alignment layer for vertical alignment excelling in aging resistance and voltage retention performance at high temperature can be prepared; and a liquid crystal display capable of high-quality displaying being stable over a prolonged period of time. There is provided a liquid crystal alignment treating agent for vertical alignment, comprising at least either one polymer among a polyamic acid obtained by reaction of a diamine of given structure containing an aromatic ring, a diamine of given structure containing an aromatic ring and a carbon to carbon unsaturated bond and a tetracarboxylic acid dianhydride containing an alicyclic structure and a polymer resulting from dehydration ring closure of the polyamic acid. There is further provided a liquid crystal display obtained with the use of the liquid crystal alignment treating agent.
