Abstract
The organic light-emitting diode () has a first electrode () with a first electric conductivity and a second electrode () with a second lower electric conductivity. An organic layer stack () for generating light is located between the electrodes (). The light-emitting diode () further comprises a current distribution layer () with a third high electric conductivity. When seen in a plan view, multiple contact regions () are located outside of an outer contour line () of the layer stack (). The second electrode () and the current distribution layer () contact each other in the contact regions (). In a current blocking region (), the current distribution layer () is located entirely within the contour line () such that the second electrode () is electrically disconnected from the current distribution layer (). The luminous intensity of a lighting surface () of the light-emitting diode () is preferably set in a controlled manner via the distribution of the contact regions () and the current blocking regions ().
