摘要：
Disclosed is an organic electroluminescent (EL) device having high emission luminance and high emission efficiency. Particularly disclosed are a blue-light emitting organic EL device, which is high in emission luminance, color purity, emission efficiency and durability, a display and an illuminating device each employing the organic EL device. The organic El device is characterized in that it comprises a light emission layer containing two or more kinds of host compounds and at least one dopant, wherein at least one of the two or more kinds of host compounds has an excited triplet energy of not less than 2.7 eV, and the dopant is a phosphorescent compound.
