Flat panel display device and fabrication method thereof
View Patent ↗A flat panel display device and fabrication method thereof are provided. The device includes a lower electrode area formed on a substrate and defining luminescent pixels, at least one auxiliary pattern formed on at least one edge area of the substrate so as to be separated from the lower electrode area, and an insulating layer formed on an area excluding the luminescent pixels so as to at least partially overlap with the at least one auxiliary pattern, thereby improving device performance and endurance by forming an insulating layer having a desirable shape.
1. A method of fabricating a flat panel display device, comprising the steps of:
forming a plurality of lower electrodes on a substrate so as to extend in one direction wherein luminescent pixels are defined over the lower electrodes;
forming a plurality of connection tabs on one edge of the substrate in a direction crossing with the extending direction of the lower electrodes so as not to be overlapped with the lower electrodes and forming at least one auxiliary pattern on an edge area of the substrate;
forming an insulating layer on an area excluding the luminescent pixels and the lower electrodes so as to be overlapped in part with the at least one auxiliary pattern; and
forming an upper electrode over the lower electrodes so as to be contacted with the connection tabs.
2. The method of claim 1 , further comprising a step of forming an organic luminescent layer on the respective luminescent pixels.
3. The method of claim 1 , further comprising a step of forming partition walls on the insulating layer between columns of the luminescent pixels in the extending direction of the lower electrodes so as to electrically isolate the upper electrode every column unit of the luminescent pixels.
4. The method of claim 1 , further comprising a step of forming an auxiliary electrode on a predetermined area of the respective lower electrodes and connection tabs wherein the auxiliary electrode has a resistance lower than that of the lower electrode and that of connection tab.
