Abstract
There is provided a polarizing plate that achieves an excellent reflection hue. A polarizing plate according to an embodiment of the present invention is used in an organic EL panel, and includes a polarizer and a retardation film. In-plane retardations of the retardation film satisfy a relationship of Re(450)<Re(550); and an angle θ formed between an absorption axis of the polarizer and a slow axis of the retardation film satisfies a relationship of 38°≦θ≦44° or of 46°≦θ≦52°.
