The invention discloses an organic light emitting diode device, a display panel and a display device. The organic light emitting diode device is mainly characterized in that existing serial top-emitting OLED devices are improved, a homojunction structure is utilized and functional layers of the top-emitting OLED devices connected in series are improved, so that each function layer comprises a hole injection layer, a hole transmission layer, a hole side light-emitting layer, an electron injection layer, an electron transmission layer, an electron side light-emitting layer and at least one group of charge producing layers a and charge producing layers b located between the hole side light-emitting layer and the electron side light-emitting layer, the hole injection layer, the hole transmission layer and the hole side light-emitting layer are sequentially arranged on the side close to an anode, the electron injection layer, the electron transmission layer and the electron side light-emitting layer are sequentially arranged on the side close to a cathode. A first light-emitting unit ...and an Nth light-emitting unit of each serial top-emitting OLED device are of homojunction structures, the using categories of organic materials are decreased, injection potential barriers of charge carriers in the devices are eliminated, the charge carrier injection efficiency and the efficiency of the devices are improved, and drive voltage of the devices is reduced.
