摘要

PURPOSE: A liquid crystal alignment agent is provided to improve response rate and transmittance, to improve electric performance and to easily control a pretilt angle.;CONSTITUTION: A liquid crystal alignment agent comprises a polyamic acid which comprises a repeating unit represented by chemical formula 1, a polyimide which comprises a repeating unit indicated in chemical formula 2, and a polymer selected from combinations thereof. In chemical formula 1 and 2, each of X^1 and X^2 is independently quadrivalent organic groups derived from alicyclic dianhydride or aromatic dianhydride, and each of Y^1 and Y^2 is a divalent organic group derived from a diamine. The polyamic acid and polyimide has a weight average molecular weight of 10,000-300,000 g/mol.;COPYRIGHT KIPO 2013
