Abstract

Disclosed is an organic EL device comprising an anode, a cathode and an organic thin film layer arranged between the anode and the cathode. The organic thin film layer has a fluorescent light-emitting layer containing a fluorescent host and a fluorescent dopant, and a first phosphorescent light-emitting layer containing a first phosphorescent host and a first phosphorescent dopant. When the triplet energy gap of the fluorescent host is expressed as EgfH and the triplet energy gap of the first phosphorescent host is expressed as EgpH1, they satisfy the following relation: EgfH > EgpH1.
