An organic electroluminescence display including: a gate line disposed on a substrate; a data line crossing the gate line; a TFT connected to the gate and data lines; a capacitor connected to the TFT; and an OLED connected to the TFT. A gate electrode of the TFT and a lower electrode of the capacitor are patterned from a first layer. A gate insulating layer disposed on the gate electrode and an insulating island disposed on the gate line are patterned from a second layer. A semiconductor island disposed on the insulating island and an active layer disposed on the gate insulating layer are patterned from a third layer. An insulating layer is disposed on the TFTs, the capacitor, and between the semiconductor island and the data line. An upper electrode of the capacitor, source/drain electrodes of the TFT, and the data line are patterned from a fourth layer.
