Transparent light emitting device with controlled emission

摘要

A light emitting device and a method for manufacturing the light emitting device are disclosed. In one example, the light emitting device includes a transparent substrate, partially transparent an anode layer or layer assembly arranged on said substrate, a light emitting layer arranged on said anode layer, and a transparent cathode layer arranged on said light emitting layer, wherein said anode layer or layer assembly includes a first surface facing said transparent substrate and a second surface facing said light emitting layer and is positioned opposite to said first surface, said first surface includes a transparent conductive material, said second surface includes first and second domains, said first domains are conductive and non-transparent, said second domains are transparent and electrically isolating, and said first domains are in direct contact with said light emitting layer and are arranged to allow electrical contact between said first surface and said light emitting layer.
