Organic light emitting diode display device and method of fabricating the same

摘要

An organic light emitting diode display device capable of improving capacitance Cst of a storage capacitor and transmittance and a method of fabricating the same are disclosed. The organic light emitting diode display device includes a driving thin film transistor (TFT) formed on the substrate, a passivation film formed to cover the TFT driver, a color filter formed on the passivation film in a luminescent region, a planarization film formed to cover the color filter, a transparent metal layer formed on the planarization film, an insulating film formed on the transparent metal layer, a first electrode connected to the TFT driver and overlapping the transparent metal layer while interposing the insulating film therebetween, an organic light emitting layer and a second electrode which are sequentially formed on the first electrode. The transparent metal layer, the insulating film, and the first electrode constitute a storage capacitor in the luminescent region.
