Abstract

A light-emitting diode arrangement comprising a plurality of semiconductor chips which are provided for emitting electromagnetic radiation from their front side (101) and which are fixed by their rear side (102)—opposite the front side—on a first main face (201) of a common carrier body (2), wherein the semiconductor chips consist of a respective substrateless semiconductor layer stack (1) and are fixed to the common carrier body without an auxiliary carrier, and to a method for producing such a light-emitting diode arrangement.
