A tandem organic electroluminescent element for an organic electroluminescent display and a display using the tandem organic electroluminescent are provided. The tandem organic electroluminescent element comprises an anode, a cathode, a first high charge injection layer, a second high charge injection layer, and at least two organic electroluminescent units. Both the first high charge injection layer and the second high charge injection layer are disposed between the anode and the cathode. The first high charge injection layer comprises a first material and is adjacent to the anode. The second high charge injection layer comprises a second material and is adjacent to the cathode. At least two organic electroluminescent units are disposed between the first high charge injection layer and the second high charge injection layer.
