    Abstract: An optoelectronic semiconductor component is specified that has a semiconductor chip having a main side, the main side comprising a plurality of emission fields that are arranged next to one another. The emission fields are individually and independently actuatable and, during operation, they are each used to couple radiation out of the semiconductor chip. The main side has reflective partitions mounted on it that are arranged between adjacent emission fields and at least partially surround the emission fields in a plan view of the main side. In addition, the main side has a conversion element mounted on it, having an underside, which faces the semiconductor chip, and an averted top. The partitions are formed from a different material from the semiconductor material of the semiconductor chip and jut out from the semiconductor chip in a direction away from the main side.
