1. A liquid crystal alignment agent, comprising:
a polymer (A), synthesized by reacting a mixture that includes a tetracarboxylic dianhydride component (a) and a diamine component (b); and a solvent (B); and wherein the tetracarboxylic dianhydride component (a) us selected from at least one tetracarboxylic dianhydride compound (a-1) having a structure of formula (I) to (III), and the diamine component (b) includes at least one diamine compound (b-1) having a structure of formula (IV): in the formula (I) to (III), the R1 represents a hydrogen atom, an alkyl group of 1 to 6 carbon atoms, or a single ring or condensed polycyclic aromatic group of 6 to 14 carbon atoms; and the R2 represents a hydrogen atom, an alkyl group of 1 to 6 carbon atoms, a single ring or condensed polycyclic aromatic group of 6 to 14 carbon atoms; in the formula (IV), the R3 independently represents a monovalent organic group; the R4 independently represents a monovalent organic group; m represents an integer of 0 to 3; and n represents an integer of 0 to 4. |
