Summary: | A polarizing plate of the present invention includes a polyvinyl alcohol-based polarizer and transparent protective films provided on both sides of the polarizer with an adhesive layer interposed between the polarizer and each transparent protective film, wherein the transparent protective film on one side comprises a lactone ring structure-containing (meth)acrylic resin and is a retardation plate having an in-plane retardation of 40 nm or more and/or a thickness direction retardation of 80 nm or more, and the transparent protective film on the other side has an in-plane retardation of less than 40 nm and a thickness direction retardation of less than 80 nm. The polarizing plate can satisfy durability and display uniformity (unevenness). |
