An organic light-emitting display device includes a capacitor lower electrode that includes a semiconductor material doped with ion impurities. A first insulating layer covers an active layer and the capacitor lower electrode. A gate electrode includes a gate lower electrode formed of a transparent conductive material and a gate upper electrode formed of metal. A pixel electrode is electrically connected to the thin film transistor. A capacitor upper electrode is at the same level as the pixel electrode. An etch block layer is formed between the first insulating layer and the capacitor upper electrode. Source and drain electrodes are electrically connected to the active layer. A second insulating layer has an opening completely exposing the capacitor upper electrode. A third insulating layer exposes the pixel electrode. An intermediate layer includes an emissive layer. An opposite electrode faces the pixel electrode.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0075217 filed with the Korean Intellectual Property Office on Jul. 28, 2011, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to an organic light emitting display device with a simplified manufacturing process and a manufacturing method thereof. Background technique [0004] A flat panel display device (such as an organic light-emitting display device or a liquid crystal display device) is fabricated on a substrate with a pattern including thin film transistors (TFTs), capacitors, interconnect lines for connecting the TFTs and capacitors, and other components. In general, to form micropatterns including TFTs or the like, a mask with micropatterns is used to transfer the micropatterns onto an array substrate on which a flat panel display device will be fabricated.
