US Patent 11177339 Organic light-emitting display device and manufacturing method thereof

An organic light-emitting display device can include a low-level voltage line; a passivation layer that lies over the low-level voltage line; a planarization layer that lies over the passivation layer; an anode and an auxiliary electrode that lie on the planarization layer and the passivation layer, the auxiliary electrode is electrically connected to the low-level voltage line; a bank layer that lies over the anode, the planarization layer and the passivation layer and defines a light-emitting area; an organic emissive layer over the light-emitting area; and a cathode disposed on the organic light-emitting layer, in which the cathode is connected to a side of a protruding portion where the auxiliary electrode protrudes from the planarization layer.
