Abstract

A light-emitting diode arrangement comprising a plurality of semiconductor chips which are provided for emitting electromagnetic radiation from their front side and which are fixed by their rear side—opposite the front side—on a first main face of a common carrier body, wherein the semiconductor chips consist of a respective substrateless semiconductor layer stack and are fixed to the common carrier body without an auxiliary carrier, and to a method for producing such a light-emitting diode arrangement.
