Abstract:
A light emitting diode comprises first and second electrodes facing each other; a first charge generation layer between the first and second electrodes; a first emitting stack including a first emitting material layer between the first electrode and the first charge generation layer and a first electron transporting layer between the first emitting material layer and the first charge generation layer; and a second emitting stack including a second emitting material layer between the first charge generation layer and the second electrode and a second electron transporting layer between the second emitting material layer and the second electrode, wherein the first charge generation layer has an electron mobility lower than that of the first electron transporting layer.
