Abstract
The organic light emitting display device includes a substrate, a thin film transistor formed on the substrate, a protective film formed to cover the thin film transistor, a color filter layer formed on the substrate exposed by removing a gate insulating layer of the thin film transistor and the protective film, an overcoat layer formed over the entire surface of the substrate to cover the color filter layer and the protective film, a drain contact hole exposing the thin film transistor by selectively removing the protective film and the overcoat layer, and a first electrode connected to the thin film transistor through the drain contact hole on the overcoat layer, a white organic light emitting layer formed on the first electrode, and a second electrode formed to cover the white organic light emitting layer.
