摘要： The embodiments of the present invention provide an organic light emitting diode device, display panel and display device. The existing top emitting series OLED device is improved with a structure of homojunctions; the functional layer of the top emitting series OLED device is also improved. The functional layer comprises a hole injection layer, a hole transport layer, a plurality of light emitting layers, an electron transport layer and an electron injection layer sequentially arranged from the anode. A charge generation layer A and a charge generation layer B are arranged between two directly adjacent light emitting layers. A homojunction is applied in each light emitting unit of the top emitting series OLED device, reducing the types of organic materials and the carrier injection barrier, improving the injection of carriers and the efficiency of the device. The driving voltage of the device is thus reduced.
