  • Liquid crystal alignment agent, liquid crystal alignment film and liquid crystal display element
    Patent number: 11453826
    Abstract: Provided are a liquid crystal alignment agent, a liquid crystal alignment film and a liquid crystal display element. The liquid crystal alignment agent at least comprises one of a polyamic acid solution and a polyimide solution. The polyamic acid solution is obtained by means of a polymerization reaction of diamine compound component A and dianhydride compound component B in a solvent, and the polyimide solution is obtained from the polyamic acid solution via a dehydration imidization treatment. The diamine component A at least comprises one of the diamine compounds represented by “formula 1”. The obtained liquid crystal alignment agent has a better liquid crystal alignment capability, an excellent effect on image sticking, and the effect that decomposition products resulting from light alignment are easy to remove.
