Beschreibung
Zusammenfassung:	PURPOSE: A liquid crystal alignment agent is provided to improve transmittance, response rate, liquid crystal orientation, and electric and optical properties, and to easily control a pretilt angle. CONSTITUTION: A liquid crystal alignment agent comprises a polymer selected from polyamic acids including a structure unit represented by chemical formula 1; polyimides including a structure unit represented by chemical formula 2; and combinations thereof. In chemical formula 1 and 2, X^1 and X^2 are the same or different from each other, and each of which is a quadrivalent organic group derived from an alicyclic anhydride or aromatic acid dianhydride; each of Y^1 and Y^2 is a divalent organic group derived from diamine; and the diamine includes an optical diamine represented by chemical formula 3.
