Abstract

An organic light-emitting component includes a substrate on which a functional layer stack is applied, the stack including a first electrode, an organic functional layer stack thereover including an organic light-emitting layer and a translucent second electrode thereover, and a translucent halogen-containing thin-film encapsulation arrangement over the translucent second electrode, wherein a translucent protective layer having a refractive index of more than 1.6 is arranged directly on a translucent second electrode between the translucent second electrode and the thin-film encapsulation arrangement, and the thin-film encapsulation arrangement is arranged directly on the translucent protective layer.
