Abstract
An organic light-emitting display device can include a low-level voltage line that receives a low-level voltage, a plurality of insulating layers that lie over the low-level voltage line, an auxiliary electrode that lies on the insulating film layer and is formed through the insulating film layer and electrically connected to the low-level voltage line, a bank layer that lies over the auxiliary electrode and defines a light-emitting area where the organic light-emitting diode is located, and a cathode of the organic light-emitting diode that lies on the bank layer and at least makes contact with the side of the auxiliary electrode.
Claims10
An organic light-emitting display device comprising:
- a low-level voltage line that receives a low-level voltage;
- a plurality of insulating layers that lie over the low-level voltage line;
- an auxiliary electrode that lies on an uppermost insulating layer among the insulating layers and is formed through the insulating film layer and electrically connected to the low-level voltage line;
- a bank layer that lies over the auxiliary electrode and defines a light-emitting area where an organic light-emitting diode is located;
- and
- a cathode of the organic light-emitting diode, the cathode disposed on the bank layer and contacting the side of the auxiliary electrode.
A manufacturing method for an organic light-emitting display device, the method comprising:
- forming a plurality of insulating layers over a low-level voltage line that receives a low-level voltage;
- forming an auxiliary electrode that is formed through the insulating layers and electrically connected to the low-level voltage line;
- forming a bank layer over the auxiliary electrode to define a light-emitting area where the organic light-emitting diode is located;
- and
- forming a cathode of the organic light-emitting diode to cover the bank layer and to make contact with the side of the auxiliary electrode.
