Abstract: Disclosed are a polarizing plate and a liquid crystal display device comprising the same. The polarizing plate comprises a protective film having a primer layer provided on one surface thereof; and a polarizer adhered to the primer layer through a photo-curable adhesive layer formed on the primer layer, thereby it shows superior adhesion between the polarizer and the protective film with excellent durability, while it does not need hydrophilic surface treatment in order to adhere the polarizer to the primer layer.

Abstract: The present invention relates to an absorptive polarizer and a method for manufacturing the same, and more particularly, to an absorptive polarizer which includes a nano-composite layer in which nanoparticles including a light absorptive element or an oxide or compound thereof are selectively contained in a block copolymer having a first block and a second block which are separately aligned therein, thereby exhibiting excellent durability even when it is exposed under hot and humid environments for a long time, and having polarization degree and transmittance substantially equal to or greater than those of any typical absorptive polarizer manufactured through drawing, as well as a method of easily preparing such an absorptive polarizer as described above at low production costs.

Abstract: Disclosed are a composite retardation plate, a composite polarizing plate including the same and a method for manufacturing the same. More particularly, a composite retardation plate is prepared by corona or plasma treatment of a face of a liquid crystal coating layer formed on a polymeric base film to improve adhesion therebetween and then directly providing a surface treatment coating layer above the coated film, thus being produced by a simple process without using a glass material while requiring neither an additional base material nor adhesive layer. Therefore, the retardation plate prepared as described above is desirably used as a retarder for a thin-film type display. The present invention also provides a composite polarizing plate including the above retardation plate and a method for manufacturing the foregoing.
