Abstract
A light emitting display device is discussed. The light emitting display device can include a first anode and a second anode spaced apart from each other, a reflective metal between the first anode and the second anode, and a bank above the reflective metal at a non-emission area to expose an emission area of each of the first anode and the second anode. The bank can include a trench having a width gradually increasing while extending downwards toward the reflective metal. In accordance with this configuration, there is an effect of preventing leakage current from flowing between the first anode and the second anode.
Claims24
A light emitting display device comprising:
- a first anode and a second anode spaced apart from each other on a substrate;
- a reflective metal between the first anode and the second anode;
- and
- a bank above the reflective metal at a non-emission area to expose an emission area of each of the first anode and the second anode, the bank comprising a trench having a width gradually increasing while extending downwards toward the reflective metal.
A method of manufacturing a light emitting display device, the method comprising:
- a first step of forming a plurality of anodes spaced apart from one another on a substrate, and forming a reflective metal among the anodes that are spaced apart;
- and
- a second step of forming a bank disposed above the reflective metal in a non-emission area to expose an emission area of each of the anodes, the bank comprising a trench having a width gradually increasing while extending downwards toward the reflective metal.
