LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM MANUFACTURED USING THE SAME, AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE LIQUID CRYSTAL ALIGNMENT FILM

摘要

PURPOSE: A liquid crystal alignment agent, liquid crystal alignment film manufactured by using the same, and a liquid crystal display device including the liquid crystal alignment film are provided to improve voltage permeability, printability, vertical orientation, and liquid crystal orientation. CONSTITUTION: A liquid crystal alignment agent includes polymer, polyamic acids which includes recurring unit represented by chemical formula 1, polyimides which includes recurring unit represented by chemical formula 2, and a combination thereof. In the chemical formula 1 and 2, X^1 and X^2 are identical or different from each other and are respectively cycloaliphatic acid dianhydrides or tetravalent organic group which is induced from aromatic acid dianhydride. Y^1 and Y^2 are identical or different from each other and are respectively divalent organic group induced from diamines.
