Provided is an organic light-emitting display panel, including an array substrate and an organic light-emitting component. The array substrate includes a plurality of driving elements, and the organic light-emitting component is arranged to be associated with the driving element. The organic light-emitting component includes an anode and a cathode, and an organic functional layer therebetween. The organic functional layer includes an organic light-emitting layer, and an electron transmission region between the cathode and the organic light-emitting layer. The electron transmission region is doped with a first dopant comprising alkaline earth metal or rare earth metal elements. The electron transmission region includes first and second electron transmission layers. The doping concentrations C1, C2 of the first dopant in the first and second electron transmission layers satisfy: 0≤C2
