Claim Text:
1. A polarizing plate, comprising: a polarizer formed of a polyvinyl alcohol-based resin, a polarizer protective film and an easy adhesion layer and an adhesive layer between the polarizer protective film and the polarizer, wherein the polarizer protective film comprises: 50 to 99% by weight of a (meth) acrylic resin having only a lactone ring structure as a ring structure with respect to the polarizer protective film; and core-shell type nanoparticles having a core layer made of a rubber polymer and a shell layer made of a glass polymer; wherein the rubber polymer comprises an alkyl(meth)acrylate; wherein the glass polymer contains at least one monomer selected from an alkyl(meth)acrylate and an aromatic vinyl monomer; and the lactone ring structure is represented by general formula (1): wherein R wherein the content of the core-shell type nanoparticles in the polarizer protective film is 1 to 30 parts by weight with respect to 100 parts by weight of the (meth)acrylic resin having the lactone ring structure; wherein the polarizer protective film is stretched, wherein the stretching is sequential stretching or simultaneous biaxial stretching with a longitudinal stretching magnification of 1.1 to 3.0 times and a lateral stretching magnification of 1.1 to 3.0 times, and wherein the easy adhesion layer is a silicone layer having a reactive functional group.
