ALIGNMENT AGENT OF A LIQUID CRYSTAL, IN WHICH LIQUID CRYSTAL ORIENTATION IS NOT AFFECTED WITH A CLEANING SOLVENT DUE TO EXCELLENT WORKABILITY, AND AN ALIGNMENT FILM OF THE LIQUID CRYSTAL INCLUDING THE SAME, AND A LIQUID CRYSTAL DISPLAY INCLUDING THE SAME

摘要

PURPOSE: An alignment agent of a liquid crystal is provided to obtain high vertical alignment power and simplicity of dropping liquid crystal and to obtain excellent adhesive force with a panel, chemical resistance, and electro-optical properties.;CONSTITUTION: An alignment agent of a liquid crystal includes a polymer which is selected from a group comprising polyamide acid marked as a chemical formula 1, a polyamide polymer marked as a chemical formula 2, and a their combination. In the chemical formula 1 and 2, R1 and R3 are a tetravalent organic group which is induced from dianhydrides selected from aliphatic cyclic acid dianhydride and aromatic acid dianhydride.;COPYRIGHT KIPO 2010
