<p>According to one embodiment, there is provided an organic light-emitting diode (10) including an anode (12) and a cathode (17) which are arranged apart from each other, a red and green emissive layer (14a) on the anode side and a blue emissive layer (14c) on the cathode side, which are arranged to be separated from each other between the anode (12) and the cathode (17), and a spacer layer (14b) which is inserted between the red and green emissive layer (14a) and the blue emissive layer (14c), and consists of a hole transport material which prevents energy transfer from the blue emissive layer (14c) to the red and green emissive layer (14a). The red and green emissive layer (14a) contains a host material having hole transportability, a red phosphorescent emitting dopant, and a green phosphorescent emitting dopant, and the blue emissive layer (14c) contains a host material having electron transportability and a blue fluorescent emitting dopant.</p> |
