Abstract

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.
