Abstract
An organic electroluminescent device (OELD) and a display incorporating the same are provided. The OELD includes an anode, a cathode, an emissive layer, a hole source and an electron source. The emissive layer is disposed between the anode and the cathode. The hole source is disposed between the anode and the emissive layer. The electron source is disposed between the cathode and the emissive layer. The electron source is made from at least an organic material and at least a salt. The salt in the electron source has a concentration with a spatial distribution such that the concentration of the salt in the part of the electron source adjacent to the cathode is higher than the concentration of the salt in another part of the electron source adjacent to the emissive layer.
