In an inorganic light emitting diode, at least one layer selected from a group consisting of an oxide layer, a nitride layer, and a metal layer is formed on an upper doping layer which is in contact with a transparent electrode, and the plasma treatment is performed on the resultant structure to form a plasma etching layer, thereby enhancing adhesion between the upper doping layer and the transparent electrode. In an organic light emitting diode, at least one layer selected from a group consisting of an oxide layer, a nitride layer, and a metal layer is formed on a plastic substrate which is in contact with a transparent electrode, and the plasma treatment is performed on the resultant structure to form a plasma etching layer, thereby enhancing adhesion between the substrate and the transparent electrode. As a result, the adhesion between the substrate and the transparent electrode or between the upper doping layer and the transparent electrode is enhanced and the layer separation from the transparent electrode is prevented, thereby improving efficiency of the light emitting diode and increasing the production yield. | 04-23-2009 |
