Embodiment 1

[0080] 100 mol% MgO, 2 mol% Li 2 CO 3 and 2 mol% GeO 2 Put in a mixer and mix well for 5 hours or more. The resulting mixture was placed in a crucible and heated in an electric furnace at 500°C for 10 hours. The resulting product was compression molded into pellets and sintered at 1300°C to prepare a deposition source.

[0081] Meanwhile, address electrodes made of copper were formed on the rear substrate with a thickness of 2 mm by photolithography. The address electrodes were covered with PbO glass to form a rear dielectric layer with a thickness of 20 μm. Next, the rear dielectric layer is made of BaAl 12 o 19 : Mn phosphor coating that emits green light.

[0082] Bus electrodes made of copper were formed on the front substrate with a thickness of 2 mm by photolithography. The bus electrodes were covered with PbO glass to form an upper dielectric layer with a thickness of 20 μm. Next, a deposition source is deposited on the front substrate by electron beam evaporat...

Abstract

Provided is a protective layer formed using at least one selected from the group consisting of a magnesium oxide and a magnesium salt and at least one selected from the group consisting of a lithium salt, a lithium oxide, a germanium oxide, and a germanium element. Provided is also a composition for forming a protective layer. When the composition is used for a protective layer of a gas discharge display device, an electrode or a dielectric can be protected from plasma ions generated by discharge of a mixed gas of Ne+Xe or He+Ne+Xe, a lower discharge voltage and a shorter discharge lag time can be obtained.

Description

[0001] Cross References to Related Patent Applications [0002] This application claims priority and benefits from Korean Patent Application No. 10-2004-0048655 filed on June 26, 2004 in the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The invention relates to a protective layer of a gas discharge display, in particular to a dielectric protective layer with excellent discharge characteristics and a forming method thereof. Background technique [0004] A plasma display panel (PDP) is a self-emitting device that is easy to manufacture as a large display, and has good display quality and fast response speed. In particular, since they are thin, like liquid crystal displays (LCDs), PDPs have drawn great attention as wall-mounted displays. [0005] figure 1 PDP pixels are shown. refer to figure 1 , each comprising a pair of first and second electrodes (each referenced 15 ), are formed on th...
