Disclosed is a polarizing plate having low moisture absorption, wherein fading deterioration of a polarizer is improved. A liquid crystal display using the polarizing plate is also disclosed. The polarizing plate is obtained by sandwiching a polarizer composed of a polyvinyl alcohol with an acrylic film (a) having a water vapor permeability of 100-500 g/m2·24 hr and a cellulose ester film (b1) containing no phosphate plasticizer or a cellulose ester film (b2) containing a phosphate plasticizer and an acid scavenger. The polarizing plate is arranged on at least one side of a liquid crystal cell, with the cellulose ester film (b1) or (B2) being on the liquid crystal cell side.
