ORGANIC ELECTROLUMINESCENT ELEMENT |
摘要 |
An organic electroluminescent element comprising a substrate and, superimposed thereon, a positive electrode, an organic layer and a negative electrode, wherein at least one organic layer is a luminescent layer containing a host agent and a doping agent and wherein an azole compound having an oxadiazole structure together with a triazole structure in the same molecule is incorporated in at least one organic layer. This azole compound can be used not only as a host agent of the luminescent layer but also in a hole inhibiting layer or electron transport layer. The thus obtained organic EL element is suitable for use in a full color or multicolor panel and as compared with the EL element using emission from singlet state, can realize high luminous efficiency and enhanced driving stability.
