Patent ID: 8519612

Claim:
An organic light emitting diode (OLED) display device, comprising: a substrate including an emission region and a non-emission region; a black matrix disposed in a region excluding a part of the emission region; a buffer layer disposed on an entire surface of the substrate; a semiconductor layer disposed on the buffer layer in the non-emission region; a gate electrode disposed on the semiconductor layer; a gate insulating layer insulating the semiconductor layer from the gate electrode and formed on the entire surface of the substrate; a first electrode formed on the gate insulating layer in the emission region; source and drain electrodes electrically connected with the semiconductor layer and the first electrode; an interlayer insulating layer insulating the source and drain electrodes from the gate electrode and exposing a part of the first electrode; a pixel defining layer exposing a part of the first electrode and disposed on the entire surface of the substrate; an organic layer disposed on the first electrode; and a second electrode disposed on the entire surface of the substrate, wherein the first electrode includes a transparent conductive oxide layer.
