摘要： The present invention relates to a COG-typed organic electroluminescent device including dummy data lines formed at different location from data lines. The COG-typed organic electroluminescent cell having a plurality of pixels formed in the luminescent areas which are cross areas of indium tin oxide films (ITO films) and metal line layers includes data line pads, dummy data lines, and a dummy data line connecting section. The data line pads each are connected to one end of the ITO films. The dummy data lines each are connected to the other end of the ITO films. The dummy data line connecting section connects the dummy data lines. In the cell, the dummy lines are formed separately from the pads, and thus the number of pins may be reduced.
