Abstract
The invention concerns a transparent light-emitting component, in particular an 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 electric voltage to the upper and the lower electrode in a switched-on state, which light is radiated in a ratio of at least approximately 4:1 through the upper or the lower electrode and where a stack, which is transparent in the visible spectral region, of dielectric layers is arranged on the side of the upper or the lower electrode.
