The present specification relates to an organic light emitting diode.

Organic light-emitting device

Disclosed is an organic light emitting diode including a cathode, an anode, a light emitting layer provided between the cathode and the anode, a first electron transporting layer including a heterocyclic compound represented by Formula 1 and provided between the cathode and the light emitting layer, and a second electron transporting layer including a host material including one or two or more of compounds represented by Formulae 3 to 5 and one or two or more n-type dopants selected from alkali metals and alkaline earth metals and provided between the cathode and the first electron transporting layer: 

An embodiment of the present invention discloses an organic light emitting diode comprising an organic layer consisting of one layer or more, which includes a transparent electrode, a reflective electrode provided facing the transparent elector, and a light emitting layer provided between the transparent electrode and the reflective electrode. Here, the light emitting layer includes two or more light emitting materials and is characterized in that the difference between the dipole moment value of one light emitting material and the dipole moment value of another light emitting material from among the light emitting materials is 1.5 Debye or more.

Organic light emitting diode
