An organic electroluminescent element is characterized by having a light emitting layer (503) containing a fluoranthene derivative and emitting green light. The fluoranthene derivative is introduced as a guest into the light emitting layer, and, by using an organic material having a fluorescence spectrum overlapping the absorption spectrum of the fluoranthene derivative, e.g., an arylanthracene derivative as a host, the organic electroluminescent element advantageously emits green light with satisfactorily excellent light emission efficiency and high color purity and has higher reliability.
一种有机电致发光元件的特点是具有一个含有
荧蒽衍
生物的发光层(503),并能发出绿光。将
荧蒽衍
生物作为客体引入发光层,并使用具有与
荧蒽衍
生物吸收光谱重叠的荧光光谱的有机材料(例如芳基
蒽衍
生物)作为宿主,有机电致发光元件就能以令人满意的优异发光效率和高色纯度发出绿光,并且具有更高的可靠性。
