Abstract: An organic electroluminescent device includes a first electrode, a hole transport region on the first electrode, an emission layer on the hole transport region, an electron transport region on the emission layer, and a second electrode on the electron transport region. The electron transport region includes a first electron transport layer on the emission layer; and a second electron transport layer on the first electron transport layer. An absolute value of difference between a highest occupied molecular orbital (HOMO) energy level of the emission layer and a HOMO energy level of the first electron transport layer is about 0.3 eV to about 1.5 eV.
