摘要：
The present invention provides an organic electroluminescent device including a pair of electrodes including an anode and a cathode, at least one of which is transparent or translucent; and one or more organic compound layers placed between the pair of electrodes, wherein at least one of the organic compound layers contains a charge transport material that satisfies the following relations: (ta−tT)/ta
