Patent ID: 8791478

Claim:
An organic light emitting display device comprising: a display panel that comprises: a plurality of pixels; a cathode layer connected to the plurality of pixels to supply a first supply voltage to the pixels; a plurality of supply voltage pads; and a plurality of cathode connection parts coupled to the cathode layer to supply the first supply voltage to the cathode layer from the plurality of supply voltage pads, wherein each of the cathode connection parts is in contact with the cathode layer through a contact area, wherein the contact area is between 10% and 90% of an overlapping area of the cathode connection part and the cathode layer; wherein each cathode connection part comprises an electrode layer that overlaps with the cathode layer, wherein the overlapping area of the cathode connection part and the cathode layer is the overlapping area between the electrode layer and the cathode layer, and wherein each cathode connection part comprises one or more voltage link lines connecting the electrode layer with respective ones of the supply voltage pads.
