Organic light emitting diode and organic light emitting display including the same
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.
