Abstract: An optoelectronic semiconductor component may include a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, a first contact element for making contact with the first semiconductor layer, and a second contact element for making contact with the second semiconductor layer. The first semiconductor layer may be arranged on a side facing away from a first main surface of the second semiconductor layer. Electromagnetic radiation may be output via the first main surface of the second semiconductor layer. The first contact element and the second contact element may each be arranged on a side of a first main surface of the first semiconductor layer. The first contact element may have a first section extending in a first direction, and a second section connected to the first section and extending in a second direction different from the first direction.
