Abstract
An organic light-emitting diode includes a carrier substrate, a scattering layer, a first electrode, an organic layer sequence with at least one active layer, and a second electrode wherein all the components are arranged in the stated sequence, the scattering layer has a higher average refractive index than the organic layer sequence, the first electrode has at least n or at least n+1 non-metal layers and n metal layers, n is a natural number greater than or equal to 1 or greater than or equal to 2, and the non-metal layers and the metal layers succeed one another alternately.
