摘要
An organic electroluminescent device includes an anode, a cathode, a light emitting layer provided between the anode and the cathode, a first organic material layer being in physical contact with the anode and doped with a p-type dopant, and a second organic material layer being in physical contact with the cathode and doped with a p-type dopant. The concentration of the p-type dopant in the first organic material layer is 50% by weight or more and less than 100% by weight.
