Abstract

The present invention relates to an organic light emitting diode including first and second electrodes facing each other; and a first emitting part including a first blue emitting layer, a second blue emitting layer, an electron transporting layer and positioned between the first and second electrode, wherein the first blue emitting layer includes a first host and a first dopant, and the second blue emitting layer includes a second host and a second dopant, wherein the first host is an anthracene derivative having a first deuteration ratio, and the second host is an anthracene derivative having a second deuteration ratio smaller than the first deuteration ratio, wherein the first dopant is a first compound represented by Formula 3, and wherein the first electron transporting layer includes at least one of a first electron transporting material represented by Formula 9 and a second electron transporting material represented by Formula 10.
