Abstract

An optoelectronic semiconductor device is specified, comprising a multiplicity of radiation-emitting semiconductor chips (2), arranged in a matrix-like manner, wherein the semiconductor chips (2) are applied on a common carrier (1), at least one converter element (3) disposed downstream of at least one semiconductor chip (2) for converting electromagnetic radiation emitted by the semiconductor chip (2), at least one scattering element (4) situated downstream of each semiconductor chip (2) and serving for diffusely scattering electromagnetic radiation emitted by the semiconductor chip (2), wherein the scattering element (4) is in direct contact with the converter element (3).
