Abstract: An organic light emitting diode (OLED) display according to the present invention includes a substrate; a driving gate electrode formed on the substrate; and a first gate insulating layer covering the substrate and the driving gate electrode. A semiconductor layer formed on the first gate insulating layer and including a switching semiconductor layer and a driving semiconductor layer separated from each other. A second gate insulating layer disposed covering the semiconductor layer. A switching gate electrode formed on the second gate insulating layer and overlapping the switching semiconductor layer. An interlayer insulating layer is disposed covering the switching gate electrode and the second gate insulating layer, wherein a thickness of the first gate insulating layer is thicker a thickness of the second gate insulating layer.
