Abstract

Disclosed is a flat panel display device and fabrication method thereof. The present invention includes a lower electrode area formed on a substrate and defining luminescent pixels, at least one auxiliary pattern formed on one at least 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 be overlapped in part with the at lest one auxiliary pattern, thereby enabling to improve device performance and endurance by forming an insulating layer having a desirable shape.

Description

technical field [0001] The invention relates to a flat panel display and a manufacturing method thereof. Background technique [0002] Insulating layers are necessary in the manufacture of flat panel displays. [0003] In flat panel displays, an organic EL (field emission) device emits light in such a way that charges are injected into an organic layer between an electron injection electrode (cathode) and a hole injection electrode (anode), where electrons and holes are paired, and light is emitted due to the reduction of these pairs. The EL device is driven by low voltage and consumes less power. [0004] In this case, an insulating layer is formed on a substrate to cover the edges of the anode which are vulnerable to damage during the fabrication of the organic EL device. [0005] When the edge of the anode is damaged, the distance between the cathode and the anode tends to shorten. Once the distance between the cathode and the anode is shortened, the organic layer bet...
