An emobdiment of the invention relates to an organic light-emitting diode, a display and illuminating device. An organic light-emitting diode capable of using flurescence blue light-emitting materials with no consideration of T1 energy, and obtaining high light-emitting efficiency is provided. According to one embodiment, there is provided an organic light-emitting diode including an anode (10) and a cathode (17) which are arranged apart from each other, an emissive layer (14) arranged between the anode and the cathode including a blue emissive layer (14a) located at the anode side and a green and red emissive layer located at the cathode side, the blue emissive layer containing a host material and a blue fluorescent dopant, and the green and red emissive layer (14b) containing a host material and a green phosphorescent dopant and/or a red phosphorescent dopant.
