An organic electroluminescence device includes an anode, a cathode, a first emitting layer and a second emitting layer that are interposed between the anode and the cathode and are in a direct contact with each other, and a first electron transporting layer between the cathode and the first emitting layer and the second emitting layer being in a direct contact with each other. The first emitting layer contains a first compound represented by a formula (1) as a first host material, the first compound having at least one group represented by a formula (11). The second emitting layer contains a second compound represented by a formula (2) as a second host material. The first electron transporting layer contains a third compound represented by a formula (3).
