Abstract: Provided are a polarizing plate for antireflection containing a polarizer, and a protective layer formed on at least one surface of the polarizer, wherein the polarizing plate has a single transmittance of 44.6% or more and a degree of polarization of 98% or more, and a dispersion in width direction of an absorption axis of the polarizer is 0.04° or less when a stretching direction of the polarizer is set to 0°, and a display device containing the polarizing plate. The polarizing plate for antireflection can minimize dispersion of optical performance and prevent the polarizer from being cut off during a preparation process while exhibiting high transmittance. Further, the polarizing plate for antireflection can be made thinner.

Abstract: A polarizing plate and a display device including the polarizing plate are disclosed. The polarizing plate is suitable for OLED and contains a polarizer, a moisture barrier layer, and a retardation layer, which are sequentially laminated. The moisture barrier layer is disposed on the opposite side of the viewing side of the polarizer and has a water vapor transmission rate of 450 g/m2·24 hr or less. The retardation layer comprises a ?/4 retardation layer, and a display device comprising the same. The polarizing plate can be made thinner, prevent reverse curling, suppress migration of iodine in a polarizer to prevent corrosion of a metal electrode of a lower panel, facilitate post-treatment such as polarizer bleaching, and prevent retardation changes even in a high-humidity environment.
