According to one embodiment, there is provided an organic light-emitting diode including an anode and a cathode which are arranged apart from each other, a red and green emissive layer on the anode side and a blue emissive layer on the cathode side, which are arranged to be separated from each other between the anode and the cathode, and a spacer layer which is inserted between the red and green emissive layer and the blue emissive layer, and consists of a hole transport material which prevents energy transfer from the blue emissive layer to the red and green emissive layer. The red and green emissive layer contains a host material having hole transportability, a red phosphorescent emitting dopant, and a green phosphorescent emitting dopant, and the blue emissive layer contains a host material having electron transportability and a blue fluorescent emitting dopant.
