Organic light emitting diode and organic light emitting device including the same

An organic light emitting diode comprising:

• a first electrode;
• a second electrode facing the first electrode;
• and
• an emissive layer disposed between the first and second electrodes and including at least one emitting material layer,
• wherein the at least one emitting material layer includes a first compound, a second compound and a third compound,
• wherein a content of each of the first compound and the second compound in the at least one emitting material layer is 10 wt % to 40 wt %, and a content of the third compound in the at least one emitting material layer is 0.5 wt % to 5 wt %,
• wherein the content of the first compound in the at least one emitting material layer is lower than the content of the second compound in the at least one emitting material layer, and
• wherein the first compound has the following structure of Formula 1 or a structure formed by linking two structures of Formula 1 via a direct bond, the second compound has the following structure of Formula 3 and the third compound has the following structure of Formula 5:
• wherein, in Formula 1,
