Abstract
An organic light-emitting diode display can include a substrate in which an emission area and a non-emission area are defined; a first transparent conductive layer, a light shielding layer, a buffer layer and a semiconductor layer sequentially laminated on the non-emission area; a gate electrode superposed on the center region of the semiconductor layer, having a gate insulating layer interposed therebetween; a drain electrode coming into contact with one side of the semiconductor layer, having an interlevel insulating layer covering the gate electrode interposed therebetween, and formed of a second transparent conductive layer and a metal layer laminated thereon; a first storage capacitor electrode disposed under the interlevel insulating layer in the emission area and formed of the first transparent conductive layer; and a second storage capacitor electrode superposed on the first storage capacitor electrode, having the interlevel insulating layer interposed therebetween, and formed of the second transparent conductive layer.
