An organic electroluminescent device comprises a pair of electrodes and a layer structure provided between the paired electrodes and including, at least, an emission layer comprising a specific type of oligomer. The layer structure may further comprise an electron injection layer and an electron transport layer, one of which comprises a specific type of oligomer. Alternatively, the layer structure may be of the type which comprises an organic layer having a charge transport interference layer in the inside thereof along with an emission layer.read more
