Organic light-emitting display apparatus and method of manufacturing the same

摘要

An organic light-emitting display apparatus includes an active layer of a thin film transistor (TFT), a gate electrode including a transparent conductive material or a metal that on the active layer, a first insulating layer on the substrate, source and drain electrodes electrically connected to the active layer, a second insulating layer between the gate electrode and the source and drain electrodes, a first conductive layer of a transparent conductive material on the first insulating layer, a second conductive layer on the first conductive layer, the second conductive layer being a metal, a third conductive layer on the second conductive layer, the third conductive layer being made of a same material as the source and drain electrodes, and being connected to the first conductive layer; and a protection layer that includes a transparent conductive oxide, the protection layer being on the third conductive layer.
