Abstract:
1. An organic electro luminescence device comprising: a thin film transistor (TFT) formed within a sub-pixel region defined by a gate line and a data line on a substrate; a passivation layer and a first electrode sequentially formed on the substrate where the TFT is formed; a contact hole formed at a predetermined portion of the passivation layer and the first electrode so as to expose a drain electrode of the TFT; an electrode separator and a buffer layer misaligned with the gate line by a predetermined position such that an emission region corresponding to the sub-pixel region and a region including the contact hole of the TFT are separated; an organic electro luminescent layer formed within a region defined by the buffer layer; and a second electrode formed on the organic electro luminescent layer and connected to the drain electrode of the TFT through the contact hole.
