RETARDATION FILMS COMPRISING A POLYMER FILM HAVING A UV-CURABLE RESIN COMPOSITION FOR ALIGNMENT FILM AND A LIQUID CRYSTALLINE COMPOUND

摘要

(1) An ultraviolet curable resin composition for an alignment film which comprises at least one (meth)acrylate compound having one or more of polar groups and one or more (meth)acryloyl groups in its molecule and a photopolymerization initiator; and an alignment film which is prepared by curing the composition with an ultraviolet ray. (2) A protective layer provided between a polymer film and a liquid crystalline compound layer for suppressing or cutting off the migration of a substance, which is present in the polymer film and capable of changing optical characteristics of the liqu id crystalline compound layer, to the liquid crystalline compound layer.
