    • The present invention relates to a polarizing plate and an image display device having the same. More specifically, the present invention relates to a polarizing plate and an image display device having the same, the polarizing plate comprising: a polarizer layer; an adhesive layer formed on at least one surface of the polarizer layer; and a phase difference film including a structure in which a liquid crystal layer, an alignment layer, and a substrate make contact in regular sequence, and the liquid crystal makes contact with the adhesive layer, wherein the alignment layer is formed by a composition for forming the alignment layer, which includes an adhesion-reinforcing agent including an isocyanate group and a (meth)acrylate group at an end portion thereof so as to form bonds with a reactive group of the surface of the substrate and a reactive group in the liquid crystal compound of the liquid crystal layer, respectively, thereby simplifying a manufacturing process, achieving excellent interlayer adhesion, and enabling the implementation of a thin polarizing plate.
    • 本发明涉及一种偏振片及具有该偏振片的图像显示装置。 更具体地,本发明涉及一种偏振板及具有该偏振板的图像显示装置,所述偏振片包括:偏振片层; 形成在所述偏振层的至少一个表面上的粘合层; 以及包括液晶层,取向层和基板以规则顺序接触的结构的相位差膜,并且液晶与粘合剂层接触,其中取向层由用于形成的组合物形成 取向层,其包含在其端部包含异氰酸酯基和(甲基)丙烯酸酯基的粘合增强剂,以与基材的表面的反应性基团和液晶中的反应性基团形成键 液晶层的化合物,从而简化制造工艺,实现优异的层间粘合,并且能够实现薄偏振片。
