Zusammenfassung:The present invention provides a polarizing plate set capable of reducing warping of liquid crystal panel in high temperature environments. The polarizing plate set comprises a front side polarizing plate disposed on the viewing side of a liquid crystal cell and a back side polarizing plate disposed on the back side of the liquid crystal cell. When a laminate in which the front side polarizing plate and the back side polarizing plate are bonded to a glass plate such that the absorption axis of the front side polarizing plate and the absorption axis of the back side polarizing plate are orthogonal to each other is heated at 85 DEG C for 250 hours, and a tensile elastic modulus in the polarizing plate transmission axis direction at 85 DEG C and a tensile elastic modulus in the polarizing plate absorption axis direction at 85 DEG C are taken as Et and Ea, respectively, the protective film in the polarizing plate on the side where the laminate is warped in a concave shape satisfies Ea, Et/Ea ≥ 1.1.
