An organic light emitting diode (OLED) display includes at least one shield electrode between a cathode layer and an OLED drive circuit. The OLED drive circuit has at least one thin-film transistor (TFT), and the shield electrode is disposed to correspond to the thin-film transistor and closer to the cathode layer, covering an entire region between the source and drain of the thin-film transistor. The shield electrode is either grounded or tied to the gate of the thin-film transistor, to thereby minimize parasitic capacitances in the pixels of the display to enhance the display performance. The presented architecture enables high density drive circuit integration in amorphous silicon or other technologies, yet preserving a high display aperture ratio.
