Abstract
Disclosed herein is an electrical light-emitting device including a transparent conductive nanorod type electrode, in which transparent conductive nanorods grown perpendicular to a light-emitting layer are used as the electrode. Hence, light is not absorbed by the electrode, and tunneling easily occurs due to nanocontact of the nanorods, thus increasing current injection efficiency, and also, total internal reflections decrease. Thereby, the light-emitting device according to this invention has light-emitting properties and luminous efficiency superior to conventional light-emitting devices, including metal electrodes or thin film type transparent electrodes.
