Abstract

A light-emitting diode (1) comprises a window layer (4) above an active layer (3), the window layer having edge webs (6) profiled in a sawtooth-shaped manner. Edge lines (11) with which the current is injected into the active layer (3) proceed above the edge webs (6). The light-emitting diode (1) is distinguished by an especially high output efficiency.
