Title: ALIGNMENT FILM MATERIAL AND MANUFACTURING METHOD FOR ALIGNMENT FILM
Abstract:
Disclosed are an alignment film material and a manufacturing method for an alignment film. The alignment film material is prepared from: polyimide; and a cross-linked polymer, the cross-linked polymer being prepared from a first component by means of a cross-linking reaction. The present invention can increase the cross-linking density of an alignment film without additionally adding a catalyst, thereby being able to effectively increase the hardness of the alignment film.
