ORGANIC LIGHT EMITTING DISPLAY DEVICE AND THE FABRICATING METHOD OF THE SAME

摘要

An organic light emitting display device and a manufacturing method thereof are provided to enhance the operation reliability of the display device by preventing a pixel shrinkage phenomenon. A TFT(Thin Film Transistor)(115) is formed on a substrate(100). A protective film(170) is arranged to cover an overall surface of the substrate. A first planarization film(180a) is formed on the protective film in an island shape and exposes a portion of the protective film. A second planarization film(180b) is formed on an overall surface of the substrate including the first planarization film. A pixel electrode(200) is formed on the second planarization film and connected to one of the source/drain electrodes of the TFT through a via-hole formed on the second planarization film. An organic film pattern(320') includes at least one light emitting layer formed on the pixel electrode. An upper electrode(330) is arranged on the organic film pattern.
