An organic light-emitting device comprising an active layer for producing radiation having a first side surface and a second side surface adjoining a corner edge. A first contact strip extends along the first side surface for injecting charge carriers of a first type into the active layer. A second contact strip extends along the second side surface for injecting charge carriers of a second type into the active layer. The first side surface has a recessed region adjoining the corner edge, and the injection of charge carriers from the first contact strip is suppressed in the recessed region.
