Abstract: An organic light emitting diode (OLED) display includes a substrate in which an emission area and a non-emission area are defined, an OLED disposed in the emission area. The OLED display further includes a thin film transistor disposed in the non-emission area, a first insulation layer overlapping the thin film transistor in the non-emission area, a first storage capacitance electrode disposed in the emission area on the first insulation layer, a second insulation layer disposed to cover the first storage capacitance electrode and the thin film transistor except a portion of the thin film transistor, said portion of the thin film transistor being exposed through the second insulation later. The OLED display further includes an organic protective layer disposed on the second insulation layer, and an anode electrode of the OLED disposed on the second insulation layer, the anode electrode electrically connected to the thin film transistor.
