Abstract:
1. An organic light emitting diode (OLED) display including a first electrode, an organic emission layer positioned on the first electrode, and a second electrode positioned on the organic emission layer, the OLED display comprising: a substrate; a thin film transistor including an active layer positioned on the substrate, a gate electrode including a gate transparent layer and a gate metal layer on the gate transparent layer, the gate transparent layer positioned on the active layer and formed with the same layer as the first electrode, and a source electrode and a drain electrode positioned on the gate electrode and connected to the active layer; a pixel defining layer positioned between the source electrode and the drain electrode, and the second electrode, the pixel defining layer including a pixel opening exposing the first electrode and a pin hole opening in the pixel defining layer and exposing at least one of the source electrode and the drain electrode; and a coated portion filling the pin hole opening.
