Abstract

An organic light-emitting display apparatus for selectively realizing circular polarization according to external light conditions, including a substrate; an organic light-emitting device on the substrate; a sealing member on the organic light-emitting device; a phase retardation layer on a surface of the substrate, the organic light-emitting device, or the sealing member; and a linear polarization layer on another surface of the substrate, the organic light-emitting device, or the sealing member, wherein the linear polarization layer is located to be closer to a source of external light than the phase retardation layer, and wherein the linear polarization layer comprises a photochromic material.
