Abstract
The present invention relates to a photo-curable composition that can provide a film, etc. showing excellent optical anisotropy even without need for separately forming a liquid crystal layer and an alignment layer, an optical anisotropic film using the same, and its preparation method. The photo-curable composition comprises a photo-alignable polymer, a noncrosslinkable liquid crystal compound and a photo-curable binder.
