Abstract: Disclosed is an organic light emitting diode and an organic light emitting display including the same, where the organic light emitting diode includes: a first electrode; a light emitting stack disposed on the first electrode; and a second electrode disposed on the light emitting stack, where the light emitting stack includes a hole transport layer and a blue light emitting layer such that the hole transport layer and the blue light emitting layer are sequentially stacked on the first electrode, where the blue light emitting layer includes a blue host material and a blue fluorescent dopant material, and the hole transport layer includes a hole transport layer material. The blue fluorescent dopant material has a higher LUMO energy level than the blue host material and the blue fluorescent dopant material has a higher HOMO energy level than the blue host material.
