Abstract
Provided are a composition for a liquid crystal alignment agent, a manufacturing method of a liquid crystal alignment film, a liquid crystal alignment film using the same, and a liquid crystal display device including the liquid crystal alignment film. More specifically, there are provided the manufacturing method of a liquid crystal alignment film capable of providing the liquid crystal alignment film in which light irradiation energy is able to be reduced, and alignment characteristic and stability are excellent and the voltage holding ratio and electrical characteristics are also excellent through a simple process including applying and drying the composition for a liquid crystal alignment agent on the substrate, directly performing light irradiation to conduct alignment treatment while a high-temperature heat treatment process is omitted, followed by curing by heat treatment, the liquid crystal alignment film, and the liquid crystal display device including the same.
