Abstract: Discussed are an organic light emitting diode display which can minimize a malfunction due to an open failure caused in a fabricating process of the organic light emitting diode display using thin film transistors as control elements, and fabricating and inspecting method of the organic light emitting diode display. Accordingly, at least one contact part is further formed by forming an upper metal layer of a dual gate structure with respect to an area in which an open failure easily occurs due to a step difference on a substrate of the organic light emitting diode display, so that a signal can be normally applied even when the open failure occurs.
