Abstract: An organic light emitting diode includes a first electrode and a second electrode overlapping each other, an emission layer disposed between the first electrode and the second electrode, and a hole transport layer disposed between the first electrode and the emission layer, the hole transport layer having a refractive index in a range of 1.0 to 1.6, in which the organic light emitting diode has a microcavity structure between the first electrode and the second electrode.
