Abstract
A liquid crystal aligning agent includes polymer(s) from at least one of polyamic acid and group of polyimides by ring closure thereof. The acid includes a first segment structure formed by first dianhydride of formula (I) and first diamine of formula (II) or (III). Xis an amorphous first soft segment. L is single bond, double bond, divalent or trivalent hydrocarbon group having 1 to 3 Cs. Yis single bond, O, NH, S, unsaturated double bond(s), or aliphatic, aromatic, heterocyclic or fused ring. One Aand one A, combined with Y, are each C. Remaining As and As are each CH, CR or N. Zis aliphatic, aromatic, heterocyclic or fused ring. As and As are each CH, CR or N. Neither of numbers of Ns in the As, As, As and As is more than two, R, Rand R are each hydrogen or aliphatic hydrocarbon group.
