LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM MANUFACTURED BY USING THEREOF, AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE FILM CAPABLE OF ENHANCING TRANSMITTANCE, RESPONSE SPEED, LIQUID CRYSTAL ORIENTATION, AND ELECTRO-OPTICAL CHARACTERISTICS

摘要

PURPOSE: A liquid crystal alignment agent, liquid crystal alignment film manufactured by using thereof, and liquid crystal display device including the film are provided to improve transmittance, response speed, electrical characteristics including voltage holding rate, and residual DC.;CONSTITUTION: A liquid crystal alignment agent includes polymers. The polymers are selected from polyamic acid including recurring unit which is represented by chemical formula 1 and polyimide including recurring unit which is represented by chemical formula 2, and combinations thereof. In the chemical formulas, X^1 and X^2 are similar or different and are respectively tetravalent organic group induced from aromatic acid dianhydride of cycloaliphatic acid dianhydride or tetravalent. Y^1 and Y^2 are similar or different and are respectively organic radical of divalent induced from diamine.;COPYRIGHT KIPO 2012
