ABSTRACT:
The invention relates to a transparent light-emitting component, in particular organic light-emitting diode, having a transparent layer arrangement in which are formed, on a substrate in a stack, planar electrodes and an organic region arranged between the planar electrodes, which organic region comprises a light-emitting layer, made from one or a plurality of organic materials. For at least one direction of incidence, a transmittance of the transparent layer arrangement for at least one wavelength subrange in the visible spectral range is greater than 50%. One of the planar electrodes has a metal layer having a thickness of less than 40 nm, and another of the planar electrodes, which is arranged opposite to the electrode in the layer arrangement, has an oxide layer made from an electrically conductive oxide material having a thickness of at least 10 nm, an intensity ratio of at least 2:1 being formed for a light emission emerging on one side of the transparent layer arrangement and a light emission emerging on an opposite side of the transparent layer arrangement.
