Organic light-emitting diode display having high aperture ratio and method for manufacturing the same

A method for manufacturing an organic light-emitting diode display, the method comprising:

• forming a first transparent conductive layer, a light shielding layer, a buffer layer and a semiconductor layer on a non-emission area of a substrate using a first transparent conductive material, a light shielding material, an insulating material and a semiconductor material, respectively, and forming a first storage capacitor electrode on an emission area of the substrate using the first transparent conductive material;
• forming a gate electrode superposed on a center region of the semiconductor layer and having a gate insulating layer interposed therebetween;
• forming an interlevel insulating layer on the overall surface of the substrate on which the gate electrode is formed;
• and
• forming, on the interlevel insulating layer, a drain electrode coming into contact with one side of the semiconductor layer and formed of a second transparent conductive layer and a metal layer laminated thereon, a source electrode coming into contact with the other side of the semiconductor layer and formed of the second transparent conductive layer and the metal layer laminated thereon, and a second storage capacitor electrode superposed on the first storage capacitor electrode and formed of the second transparent conductive layer of the drain electrode, extended to the emission area,
• wherein the buffer layer and the semiconductor layer are patterned to be disposed on the light shielding layer and not to be disposed on the first storage capacitor electrode.
