Abstract: A polarizing plate and a display device including the same are provided. A polarizing plate includes a polarizer comprising an absorption axis and a transmission axis that intersect each other, a first retardation layer disposed on a surface of the polarizer, and a second retardation layer disposed on another surface opposite to the surface of the polarizer. An in-plane retardation value of the second retardation layer is greater than about 20 nm and less than about 100 nm. An angle between the absorption axis of the polarizer and a retardation axis of the second retardation layer is in a range of about 10° to about 45°.
