1. Transparent light-emitting component, in particular organic light-emitting diode (OLED), with a layer arrangement in which a light-emitting organic layer is arranged between an upper and a lower electrode, the layer arrangement being transparent in a switched-off state and emitting light which is produced in the light-emitting organic layer by applying an electrical voltage to the upper and the lower electrode in a switched-on state and which is radiated, which light is radiated in a ratio of at least approximately 4:

  • 1 through the upper or the lower electrode, characterized in that a stack, which is transparent in the visible spectral region, of dielectric layers of two or more materials with different refractive indices is arranged on the side of the upper or the lower electrode.
