Abstract

See full text

A foldable circular polarizing plate includes a polarizer and a foldable compensation film disposed on one surface of the polarizer, wherein in-plane retardations of the liquid crystal layer at 450 nm, 550 nm, and 650 nm wavelengths satisfy Relationship Equations 1 or 2, the compensation film is configured to absorb light in a wavelength region of less than or equal to 420 nm, and a reflection color in a CIE-Lab color coordinate system satisfies Δa*b*≤5.0 and a foldable organic light emitting diode display including the same.
