The front substrate is formed with an anode (78). The rear substrate is formed with a cathode (71) facing the anode. Several sidewalls (72) are interposed between the front substrate and the rear substrate. A plurality of getter devices (82) are arranged on the front substrate. Thereby, a chamber between the front substrate and the rear substrate is maintained as a low-pressure vacuum. Each of the getter devices includes a base (820), a getter layer (822) comprised of non-evaporable getter material formed thereon, and securing wires (84) arranged on the base. ## Claims ### Claim 1 A flat panel display comprising: a first substrate comprising a middle region, a first edge region and a second edge region, the first edge region and the second edge region being at opposite sides of the middle region;
