摘要： A liquid crystal alignment agent and a preparation method thereof, a liquid crystal alignment film and a preparation method thereof, and a liquid crystal cell are provided. A piperazine monomer is added to a liquid crystal alignment agent, a bulk resistance value and a surface resistance value of a liquid crystal alignment agent material can be reduced, and the ability of the liquid crystal alignment agent material to release residual charges can be effectively improved, thereby increasing the reliability and stability of an electronic product. The liquid crystal cell using the liquid crystal alignment agent has advantages such as high voltage holding ratio (VHR) and low residual voltage.
