Abstract

A radiation-emitting arrangement comprises, in particular, a carrier element (1) having an at least partly non-transparent main surface (10) and arranged on the carrier element (1), an organic radiation-emitting component (2) having an organic layer sequence (23) with an active region between an at least partly transparent first electrode (21) and an at least partly transparent second electrode (22). The active region (29) is suitable for generating electromagnetic radiation (91, 93) in a switched-on operating state. The radiation-emitting arrangement has a radiation exit area (3) for emitting the electromagnetic radiation (92, 93) on that side of the organic radiation-emitting component (2) which faces away from the carrier element. (1) The at least partly non-transparent main surface (10) of the carrier element (1) is perceptible by an external observer through the radiation exit area (3) in a switched-off operating state of the organic radiation-emitting component (2).
