Abstract
The present invention relates to a full color organic electroluminescent device and a method for fabricating the same and provides a full color organic electroluminescent device. The invention reduces misalignment errors caused by fine patterning of the emitting layer by reducing the steps of the fine patterning process. In particular, the blue emitting layer functions as a hole inhibition layer which results in superior color purity and improved stability for the color organic electroluminescent device. The use of such a blue emitting layer also reduces the manufacturing steps. The device comprises a substrate; a first electrode pattern formed on the substrate; a red emitting layer formed by patterning a red emitting material on a red pixel region of the first electrode pattern and a green emitting layer formed by patterning a green emitting material on a green pixel region of the first electrode pattern. A blue emitting layer is applied over the entire substrate, over the upper parts of the red and green emitting layers and a second electrode is formed on an upper part of the blue emitting layer.
