Disclosed is a method of producing a liquid crystal aligning layer, a liquid crystal aligning layer produced using the same, and a liquid crystal display including the liquid crystal aligning layer. In the liquid crystal aligning layer that is produced using the method, ultraviolet rays are radiated on movable chains of a polyamic acid polymer while the polyamic acid polymer is not imidized to perform alignment, and heat treatment is then performed to conduct imidization. Thus, thermal stability is excellent, residual images are not formed, and alignment of liquid crystals is excellent.
本发明公开了一种制备液晶定向层的方法,使用该方法制备的液晶定向层以及包括该液晶定向层的液晶显示器。在使用该方法制备的液晶定向层中,当聚
酰亚胺酸聚合物未进行亚
酰亚胺化时,对聚
酰亚胺酸聚合物的可移动链进行紫外线照射以进行定向,然后进行热处理以进行亚
酰亚胺化。因此,热稳定性优异,不会形成残留图像,液晶的定向效果也很好。
