Abstract

The embodiment of the invention provides an organic light-emitting device and a method of manufacturing the organic light-emitting device, after the hierarchical structure of the organic light-emitting device is inverted, a transparent organic layer and a conductive layer are further added, and the conductive layer and a reflective cathode layer are in lap joint. By additionally arranging the transparent organic layer, the micro-cavity structure of the organic light-emitting device can be ensured not to be changed basically after being inverted compared with the micro-cavity structure before being inverted, so that photons generated by the light-emitting layer can be emitted out of the organic light-emitting device, and the external quantum efficiency of the inverted organic light-emittingdevice is improved. By additionally arranging the conductive layer, electrons generated by the reflective cathode layer can be injected into the light-emitting layer through the conductive layer, anda problem that the higher voltage needs to be applied due to poor conductivity of the transparent organic layer is solved. Due to the design, normal luminescence of the organic light-emitting deviceunder normal voltage can be realized on the premise of ensuring that the external quantum efficiency of the inverted organic light-emitting device is not reduced basically.
