Abstract
An organic electroluminescent device and methodology of fabricating the same includes first and second substrates facing and spaced apart from each other, the first and second substrates having a display region and a peripheral region, the display region including a plurality of pixel regions and a dummy pixel region; driving thin film transistors respectively adjacent to each of the plurality of pixel regions on the inner surface of the first substrate; first connection electrodes respectively connected to the driving thin film transistors; a first electrode on an entire inner surface of the second substrate; a sidewall on the first electrode at a boundary of each of the plurality of pixel regions and the dummy pixel region; an organic electroluminescent layer on the first electrode; second electrodes on the organic electroluminescent layer so that a second electrode is present in each of the plurality of pixel regions and the dummy pixel region, respectively, the second electrodes in each of the plurality of pixel regions are respectively connected to the first connection electrodes; and a sealant attaching the first and second substrates.
