Abstract: 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.

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°.
