Abstract
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.
