Abstract: A light-emitting diode includes a first electrode, a second electrode, a light-emitting layer, and a hole transfer layer. The light-emitting layer is disposed between the first electrode and the second electrode. The hole transfer layer is disposed between the light-emitting layer and the second electrode. The hole transfer layer includes an organic material. At least one of tellurium or a telluride compound of a transition metal is doped in the organic material included in the hole transfer layer.
