ABSTRACT:
A diamine-containing polyamic acid alignment layer material provided by the polymerization of aromatic diamine and dianhydride, and having an excellent coating, adhesion and stability. After the polyamic acid alignment layer material is coated and cured at a high temperature, a polyamic acid alignment layer having a pretilt angle of below 2 degrees is formed due to a close ring reaction. The polyamic acid alignment layer with a low pretilt angle can be used in a TN (twisted nematic) type liquid crystal display.
