Abstract
A polarizing plate, a method for manufacturing the same, and an optical display including the same are disclosed. The polarizing plate includes a polarizer, a protective coating layer on one surface of the polarizer, and an adhesive layer on one surface of the protective coating layer. The polarizing plate satisfies inequality 1. Rmax−Rmin≤0.02 (1) In Inequality 1, Rmax is the maximum index of refraction among the indexes of refraction of the polarizer, the protective coating layer and the adhesive layer, and Rmin is the minimum index of refraction among the indexes of refraction of the polarizer, the protective coating layer and the adhesive layer.
