Abstract:
1. A light emitting device comprising: a semiconductor light emitting diode which comprises a first nitride semiconductor layer of an n-type, a second nitride semiconductor layer of a p-type, and a first active layer between the first and second nitride semiconductor layers; a nano light emitting diode array which comprises a plurality of nano light emitting diodes on the semiconductor light emitting diode, each of the plurality of nano light emitting diodes including a second active layer; a first electrode at an end portion of the first nitride semiconductor layer; a first transparent electrode layer on the second nitride semiconductor layer, the first transparent electrode layer being between the plurality of nano light emitting diodes; a second electrode at an end portion of the first transparent electrode layer; a second transparent electrode layer on the plurality of nano light emitting diodes; an insulation member between the first transparent electrode layer and the second transparent electrode layer, the plurality of nano light emitting diodes extending through the insulation member and terminating at the second transparent electrode layer so as to not extend into the second transparent electrode layer; and a third electrode at an end portion of the second transparent electrode layer, the third electrode being between the first electrode and the second electrode, the third electrode being closer to the first electrode than the second electrode, wherein the first active layer emits light of a first wavelength and the second active layer emits light of a second wavelength that is longer than the first wavelength, the light emitting device configured such that the light of the first wavelength and the light of the second wavelength mix to produce white light or pseudo-white light.
