Abstract

An optoelectronic semiconductor component includes a carrier which has an upper side and a lower side opposite to the upper side. At least one radiation-emitting semiconductor device is disposed on the upper side and has a radiation emission surface, through which at least a portion of the electromagnetic radiation, which is generated during operation of the semiconductor device, leaves the semiconductor device. A radiation-absorbing layer is arranged to absorb ambient light, which impinges upon the component, such that an outer surface of the component facing away from the carrier appears black at least in places.
