Abstract
The described technology relates to an organic light emitting diode including: a first electrode; a second electrode overlapping the first electrode; an organic emission layer between the first electrode and the second electrode; and a capping layer on the second electrode, wherein the capping layer has an absorption rate of 0.25 or more for light having a wavelength of 405 nm, thereby preventing degradation of the organic emission layer by blocking the light of the harmful wavelength region and providing the organic light emitting diode in which a blue emission efficiency is not deteriorated.
