Patent ID: 8299478

Claim:
An organic light emitting diode (OLED) display device, comprising: a substrate; a thin film transistor (TFT) on the substrate, the TFT including a semiconductor layer, a gate electrode, and source and drain electrodes; a first electrode electrically connected to one of the source and drain electrodes; a pixel defining layer on the substrate, the pixel defining layer exposing the first electrode and having a reversed trapezoidal shape, such that the pixel defining layer has a lower surface facing the substrate, and an upper surface facing away from the substrate and projecting past the lower surface to form an overhang; an emitting layer on the exposed first electrode; and a second electrode on the emitting layer, the second electrode including a first portion that overlaps the upper surface of pixel defining layer, and a second portion that projects past the overhang of the pixel defining layer, wherein the first portion and the second portion are continuous.
