Abstract

A light emitting diode according to embodiments of the present disclosure includes a first electrode, a second electrode opposite the first electrode, an emission layer between the first electrode and the second electrode, the emission layer including a quantum dot, a first charge transfer layer between the first electrode and the emission layer, a second charge transfer layer between the second electrode and the emission layer, and an insulating layer in at least one position between the first charge transfer layer and the emission layer, and/or between the second charge transfer layer and the emission layer, wherein the insulating layer includes an inorganic material. The light emitting diode and a display device including the same show improved life characteristics and emission efficiency properties.
