A polarizing plate of the invention comprises a polarizer; and a transparent protective film provided on at least one side of the polarizer with an adhesive layer interposed therebetween, wherein the adhesive layer is formed of an adhesive for polarizing plate comprising: a resin solution comprising a polyvinyl alcohol-based resin, a crosslinking agent and a colloidal metal compound with an average particle size of 1 nm to 100 nm, wherein 200 parts by weight or less of the colloidal metal compound is added to 100 parts by weight of the polyvinyl alcohol-based resin, and the transparent protective film provided on at least one side is a retardation plate having a front retardation of 40 nm or more and/or a thickness direction retardation of 80 nm or more. The polarizing plate can reduce the occurrence of knicks.
