Abstract

The light-emitting diode comprises a first electrode intended to inject carriers of a first type into a stack of the light-emitting diode and arranged on an emissive face of the stack, a second electrode intended to inject carriers of a second type into the stack, and an emissive surface delimited by areas of the emissive face of the stack not covered by the first electrode. The first electrode is configured in such a way that any point of the emissive surface is situated no more than a predetermined distance from the first electrode dependent on the spreading length of the light-emitting diode. The method comprises a step of determining the spreading length of the light-emitting diode intended to be equipped with the first electrode and a step determining a characteristic of the first electrode from the determined spreading length.
