Zusammenfassung:An organic light emitting device is provided. The organic light emitting device includes a first electrode layer, a second electrode layer and a light emitting material layer. The second electrode layer is disposed opposite to the first electrode layer. The light emitting material layer is disposed between the first electrode layer and the second electrode layer, and includes an organic light emitting material and an electron transport material, wherein the electron transport material includes a compound represented by a formula (1) below: in which a group A represents an aromatic ring, a is 1, and a group B represents a nitrogen containing five-membered heterocyclic group and derivatives thereof, and has at least one nitrogen atom connected to a meta-position of the group A.
