    摘要： The present application relates to a polarizing plate having a polarizing film in which a light absorption axis is formed in one in-plane direction; a protective film formed on one side of the polarizing film; and a pressure-sensitive adhesive layer formed on the other side of the polarizing film, where the total thickness is 200 μm or less, and a ratio of (SPro/SPVA) of a shrinkage force (SPVA) of the polarizing film in the in-plane direction parallel to the light absorption axis direction and a shrinkage force (SPro) of the protective film in the in-plane direction perpendicular to the light absorption axis direction is in a range of 0.1 to 5. The present application can provide a polarizing plate which does not cause cracks or the like while having a thin thickness, does not induce warping or twisting in itself and does not induce the above problems even when applied to a display device such as an LCD or OLED.

    摘要： The present application relates to a polymer film and a method for producing a polarizing plate. The present application can provide a polymer film satisfying optical and mechanical durability required in a polarizing plate effectively and capable of forming a polarizing plate without causing bending when applied to a display device, and a method for producing a polarizing plate to which the polymer film is applied. The present application can provide a polymer film capable of realizing the required optical and mechanical durability without causing bending even in a polarizing plate applied to a thin display device and/or a thin polarizing plate, and a method for producing a polarizing plate to which the polymer film is applied.
