Abstract
An organic electroluminescent display device can compensate for voltage drop of power supply voltage line by asymmetrically arranging a plurality of contact hole for connecting cathode electrodes and cathode power supply line. The organic electroluminescent display device may include first power supply line for supplying power supply voltage to pixels, and second power supply line for supplying voltage to an electrode on the upper side of the pixel (the supply line can include a region superposed on the electrode). The second power supply line may include a plurality of contact holes through which the second power supply line is connected to the electrode. The plurality of contact holes may be asymmetrically arranged with respect to a bisector of the superposition region of the second power supply line and electrode.
