Abstract:
There is provided a circularly polarizing plate for an organic EL display apparatus, which has an excellent antireflection function and has an excellent organic EL panel-protecting function. A circularly polarizing plate according to the present invention is used in an organic EL display apparatus. The circularly polarizing plate includes in this order: a polarizer; a retardation layer functioning as a λ/4 plate; a barrier layer; and a pressure-sensitive adhesive layer having a barrier function. An angle formed between an absorption axis of the polarizer and a slow axis of the retardation layer is from 35° to 55°.

Claim (Index 1):
A circularly polarizing plate for an organic EL display apparatus, comprising in this order:\n a polarizer; a retardation layer functioning as a \u03bb/4 plate; a barrier layer; and a pressure-sensitive adhesive layer having a barrier function, wherein an angle formed between an absorption axis of the polarizer and a slow axis of the retardation layer is from 35\u00b0 to 55\u00b0, and a ratio K/I of a potassium content (wt %) to an iodine content (wt %) in the polarizer is from 0.180 to 0.235.
