An organic light-emitting diode display panel and a display device are provided. By disposing the electrode layer in each light transmissive area within the electronic-component display area as the transparent electrode layer, external light passes through the transparent electrode layer to reach the electronic component located below the display screen, and the electronic-component display area can be displayed normally without removing the display material above the electronic component, that is, the boring is not required, thereby solving the defect that the prior art requires boring, and realizing the full-screen.
