    Abstract: The present disclosure relates to a light emitting diode that includes a charge control layer disposed between a charge transfer layer and one electrode and including polysiloxane-based material chemically bonded to a surface of the charge transfer layer and a light emitting device having the same. The charge control layer is configured to remove a surface defect of the charge transfer layer, to transport charges stably, and to reflect a part of light passing through the charge transfer layer, and thereby enhancing out-coupling efficiency. In addition, the charge control layer regulates a charge flow from the electrode to the charge transfer layer, so that charges may be injected into an emitting material layer in a balanced manner.
