  • Liquid Crystal Alignment Agent and Liquid Crystal Alignment Film Manufactured Using the Same
    Publication number: 20100151155
    Abstract: The liquid crystal alignment agent according to one embodiment of the present invention includes a soluble polyimide polymer of Formula 1 and a solvent. The soluble polyimide polymer has a number average molecular weight of about 10,000 to 500,000 g/mol, and a polydispersity of about 1.2 to about 1.75. The liquid crystal alignment agent can have good printability on a substrate, and thereby can provide a liquid crystal alignment film that can have excellent film uniformity, even though its predrying temperature is varied.
