Abstract: Disclosed is an organic electroluminescence device. The device includes an anode; a cathode; and a first light-emission layer disposed between the anode and the cathode and configured for emitting blue light. The first light-emission layer comprises a host composition and a blue dopant. The blue dopant includes at least one compound represented by Chemical Formula D. The host composition contains a first host compound and a second host compound. The first host compound has a triplet energy level higher than a triplet energy level of the blue dopant, while the second host compound has a triplet energy level lower than the triplet energy level of the blue dopant. In Chemical Formula D, each of Ra, Rb, Rc, Rd and Re independently is the same as defined in the present specification.
