摘要： Disclosed herein is an LC aligning agent using diamine having dendron side chains. In detail, the present invention relates to a composition for an LC alignment film which employs diamine having dendron side chains to produce polyamic acid, followed by imidization. When the LC alignment film is applied to a liquid crystal display device, high heat resistance, high penetration in a visible ray range, excellent alignment, and a high voltage holding ratio are assured. Even though it contains a small amount of functional diamine, a high pretilt angle can be assured. Thus, the pretilt angle is easily controlled and a vertical aligning force is improved.

摘要： Disclosed herein is a novel functional diamine compound having a dendron structure, polyamic acid which is produced using functional diamine, aromatic cyclic diamine, aliphatic cyclic acid dianhydride, and aromatic cyclic acid dianhydride, polyimide which is produced by imidizing polyamic acid, and an LC alignment film produced using polyimide. Even if the diamine compound is used in a small amount, it is possible to realize a high pretilt angle, thus the pretilt angle is easily controlled. Therefore, it can be used to produce an LC alignment film using a twisted nematic (TN) mode, in which the pretilt angle of liquid crystal is low, and a vertically aligned (VA) mode, which requires a high pretilt angle of about 90°.
