FIG7 is a schematic cross-sectional view of an organic light emitting diode of the present disclosure. As shown in FIG7, an organic light emitting diode D includes the first and second substrates 160 and 164, which face each other, and the organic emitting layer 162 therebetween. The organic emitting layer 162 includes an EML 340, which includes first and second layers 342 and 344 and is positioned between the first and second electrodes 160 and 164, a HTL 320 between the first electrode 160 and the EML 340 and an ETL 360 between the second electrode 164 and the EML 340.  FIG8 is a schematic cross-sectional view of an organic light emitting diode of the present disclosure. As shown in FIG8, an organic light emitting diode D includes the first and second substrates 160 and 164, which face each other, and the organic emitting layer 162 therebetween. The organic emitting layer 162 includes an EML 440, which includes first to third layers 442, 444 and 446 and is positioned between the first and second electrodes 160 and 164, a HTL 420 between the first electrode 160 and the EML 440 and an ETL 460 between the second electrode 164 and the EML 440.
