The present invention provides a polarizing plate which can inhibit uneven display and yellowing even when the polarizing plate is applied to a liquid crystal panel and prevent charring during the film forming, and a liquid crystal display device. The polarizing plate of the invention is provided with transparent protective films on both surfaces of polyvinyl alcohol polarizing plate and spacing an adhesive agent layer. The first transparent protective film of one surface contains a (methyl) acrylic resin, and an ultraviolet light absorber. The (methyl) acrylic resin has an unsaturated carboxylic alkyl ester unit and a glutarimide unit represented by a general formula (1). The midization rate is 2.5-5.%, the acid value is 0.10-0.50mmol/g, and an acrylate unit is not more than 1 wt%. The second transparent protective film of the other surface is a phase different plate containing cellulose esters and satisfying a relation of nx>ny>nz.
