Organic electroluminescent device

Abstract

In an organic electroluminescent device constructed by providing at least an emitting layer and a carrier transport layer using an organic material between a hole injection electrode and an electron injection electrode, at least one of the emitting layer and the carrier transport layer contains a chelate compound of a chromone derivative with zinc or aluminum, a chelate compound of a 3-hydroxyflavone derivative with a metal, a chelate compound composed of an 8-quinolinol derivative dimer and another ligant which are coordinated to a metal, or a chelate compound composed of two 8-quinolinol derivatives coordinated to a metal and one halogen bonded thereto.
