The invention discloses a fabrication method of the double-sided luminescence type organic light-emitting diode, comprising the following steps. Firstly, a transparent substrate is provided; secondly, a first transparent electrode and an organic luminescent layer are formed on the transparent substrate in order; and then a second transparent electrode is formed on the organic luminescent layer. The procedure of forming the second transparent electrode comprises that a first film layer is formed on the organic luminescent layer, and the first film layer is made of an alkali metal compound or an alkaline earth metal compound; a second film layer is formed on the first film layer, and the second film layer is made of a metal material with the thickness of 20 angstrom to 50 angstrom; Finally,a plasma diffusion deposition process or an ionic thermal evaporation process for forming a third film layer on the second film layer is carried out, and the third film layer is made of a transparentconductive ...
