ABSTRACT:
Provided is a light emitting diode and method for fabricating the same, and a display device using the same, wherein the light emitting diode at least comprises a high refractive index layer on a light transmissive substrate; and an organic electroluminescence (EL) element formed of one organic thin layer or a plurality of organic thin layers interposed between a transparent first electrode and a second electrode formed on the high refractive index layer, and the high refractive index layer has a refractive index higher than that of an emitting layer or has a refractive index of 1.65 or more, and an interface between the high refractive index layer and the light transmissive substrate is roughed to have its center line average roughness in a range of 0.01 μm to 0.6 μm so that light leakage is be prevented and light extraction efficiency becomes higher.
