Abstract

An optoelectronic device, in particular an at least semi-transparent pane for example for a vehicle, comprises: a cover layer, a carrier layer, an intermediate layer between the cover layer and the carrier layer, wherein at least one and preferably a plurality of optoelectronic light sources, in particular μLEDS, is arranged on at least one surface of the intermediate layer and/or is at least partially embedded in the intermediate layer, wherein the intermediate layer is adapted such that light emitted by the optoelectronic light sources at least partially spreads in and along the intermediate layer and exits the intermediate layer within and/or at a pre-set distance to the respective optoelectronic light source in a direction through the cover layer and/or through the carrier layer.
