The constituent for liquid crystal photo alignment which includes the origoimido or origoamido Acid which the maleimide (maleimide), the Nagy imido (nadimide

摘要

The present invention, this and liquid crystal alignment film, liquid crystal alignment composition comprising oligoamide or acid oligoimide containing functional groups capable of photo-curing or heat-curing at least one end of oligoamic acid backbone or oligoimide, produced by this The present invention relates to a liquid crystal display including. By using oligoamic acid or oligoimide instead of polyimide normal, functional groups capable of photo-curing or heat-curing at least one end of the main chain is introduced, a liquid crystal alignment composition according to the present invention uses polyimide It is possible to minimize degradation by-products that are generated during, orientation, thermal stability and has an excellent afterimage improvement.
