ABSTRACT:
A full-color organic light emitting diode display device and a method of fabricating the same. The display device includes a substrate having red, green and blue light emitting regions, a first electrode on the substrate, an organic layer on the first electrode and including red, green and blue light emitting layers respectively corresponding to the red, green and blue light emitting regions, and a second electrode on the entire surface of the substrate. Here, the organic layer includes a hole injection layer and an electron transport layer, and the organic layer in the red light emitting region includes a hole suppression layer including a material in the electron transport layer. The method includes forming the hole suppression layer on the red light emitting layer in the red light emitting region. In the method, the hole suppression layer is formed of a material for forming the electron transport layer.
