Abstract
An alignment film material and a method of producing an alignment film are described. The alignment film material has polyimide and crosslinked polymer. The crosslinked polymer is formed from a first component through a crosslinking reaction. A crosslink density of the alignment film can be enhanced without additionally adding a catalyst, so as to increase a hardness of the alignment film.
