RETARDATION FILM AND IMAGE DISPLAY DEVICE HAVING SAME

摘要

The present invention relates to a retardation film and an image display device having the same and, more specifically, to a retardation film comprising a liquid crystal layer and a primer layer which are bonded by chemical bonding, wherein the chemical bonding is formed by a hydroxyl group and/or a carboxyl group on the surface of the primer layer and an isocyanate group and a (meth) acrylate group at the end of an adhesion-reinforcing agent included in the liquid crystal layer, such that the retardation film has a very high adhesive strength between the respective layers thereof.
