A backlighting unit comprises a carrier having a top side arranged parallel to an x-y-plane, a reflector assemblage arranged over the carrier in a z-direction, an optical assemblage arranged over the reflector assemblage in the z-direction, and a diffuser arranged over the optical assemblage in the z-direction. A cell of the backlighting unit comprises a section of the carrier having an optoelectronic semiconductor chip arranged on the top side, a reflector of the reflector assemblage, an optical element of the optical assemblage, and a section of the diffuser. The reflector has a concave mirror surface. The optical element has a front side facing the reflector and a rear side facing away from the reflector. The front side is subdivided into front-side surface sections arranged in a matrix-type fashion. The rear side is subdivided into rear-side surface sections arranged in a matrix-type fashion.
