ABSTRACT:
A heat resistant polymer composition, an alignment layer formed using the same, and an LCD having the alignment layer are provided. The heat resistant polymer composition includes 10-25% by weight of a polyimide resin or polyamic acid, 0.1-1% by weight of an adhesive agent, and balance of a solvent. The adhesive agent improves thermal stability. Thus, the LCD having the alignment layer formed using the same can accomplish a desirable pre-tilt angle of liquid crystals and desirable alignment properties of liquid crystal molecules.
