Abstract
The present disclosure relates to a liquid crystal alignment agent composition including: a polymer for liquid crystal alignment agent and a crosslinker compound in which a terminal crosslinking functional group is capped with a silicon-containing thermally removable protecting group, wherein a change in the number of particles during storage is lower than a certain level, a method for preparing a liquid crystal alignment film using the liquid crystal alignment agent composition, and a liquid crystal alignment film and a liquid crystal display device using the liquid crystal alignment agent film.
