The present invention provides a free radical polymerizable liquid crystal alignment agent having superior coating ability, a manufacturing method, which comprises the process of coating the liquid crystal alignment agent onto a substrate, carrying out dehydration/ring-closure and free radical polymerization, enables obtaining a liquid crystal alignment film with superior reliability, superior voltage holding ratio and easy control of pretilt angle, and enables the manufacture of a liquid crystal display element provided with a liquid crystal alignment film. The free radical polymerizable liquid crystal alignment agent comprises a molecular compound containing at least 2 polymerizable maleamic acid groups and an organic solvent.
A method of forming a liquid crystal alignment film comprising a process of coating a liquid crystal alignment agent onto a substrate, and then processing said alignment agent with dehydration/ring-closure reaction and free radical polymerization, wherein said liquid crystal alignment agent comprises a molecular compound containing at least 2 polymerizable maleamic acid groups (A), and an organic solvent (B).
