  With social progress and technological development,liquid crystal display (LCD) devices have been applied in a wide range of fields because of its advantages,such as small size,low power consumption,and low radiation.Liquid crystal (LC) alignment layer plays an important role in high-quality LCD.Polyimides (PI) films are widely used as LC alignment layers in LCD for their advantageous properties such as good thermal stability,corrosion resistance,excellent optical transparency,and so forth.
