Organic EL element and organic EL display

摘要

The organic EL element of the invention includes an organic thin layer which includes at least a light-emitting layer, between a positive electrode and a negative electrode, wherein a layer in the organic thin layer includes a 1,3,6,8-tetraphenylpyrene compound expressed by the following structural formula (1) and a triphenylbenzene derivative expressed by the following structural formula (2). Preferably, the triphenylbenzene derivative is 1,3,5-tris[4-(N-carbazolyl)phenyl]benzene (TCPB). In the structural formula (1), R¹ to R⁴ represent one of a hydrogen atom, alkyl group, cycloalkyl group, and aryl group. In the structural formula (2), R⁵ represents a carbazole skeleton expressed by the following structural formula (3). In the structural formula (3), R⁶ and R⁷ represent a hydrogen atom, or a substituent group.
