  • Publication number: 20070128378
    Abstract: 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.
