Abstract: An organic electroluminescence device including an anode, a cathode and a light-emission layer. The light-emission layer includes a stack of a blue light-emission layer and a red/green light concurrent-emission sub-stack. Further, the red/green light concurrent-emission sub-stack includes a stack of a red light-emission layer and a green light-emission layer. The red light-emission layer contains a red host compound including an arylamino group-substituted spirobisfluorene compound. Further, the green light-emission layer contains a green host compound including a mixture between a first green host compound and a second green host compound. Also, the first green host compound includes a bis-carbazole based compound, and the second green host compound includes a carbazole-based compound.
