Abstract:
An organic light emitting diode includes: a first electrode; a first hole transporting layer on the first electrode; a first emitting material layer on the first hole transporting layer, the first emitting material layer including a first host with a first dopant, wherein an energy level of a lowest unoccupied molecular orbital of the first dopant is higher than an energy level of a lowest unoccupied molecular orbital of the first host; a first electron transporting layer on the first emitting material layer; and a second electrode on the first electron transporting layer, wherein an energy level of each of the first hole transporting layer and the first electron transporting layer is higher than an energy level of a triplet state exciton of the first emitting material layer.
