PURPOSE:To eliminate the need for a mask vacuum evaporation method that will not form a protection layer and obtain gas discharge panel with high reliability by providing a conductor layer with a coarse surface as a leak electrode that leaks the wall charge cumulated on a dielectric layer. CONSTITUTION:Leak electrodes 13 and 16 are formed by coating a glass substrate located at the inside to be coated with a sealing agent when the peripheral sections of the glass substrates 11 and 15 are coated with the sealing agent while the sections are being sealed after a dielectric layer 12 is formed and simultaneously baking the glass substrates in a process where the subsequent agent is baked. The surface of leak electrodes 13 and 16 formed in such a way is at least 0.5mum or more in a difference in the recessed and protruded sections of the surface. Even when a protective layer made of MgO is formed thick on this leak electrode 13, cracks enter the inner part of the protective layer and the wall charge cumulated on the surface of the propective layer is leaked. As a result, an unstable process such as mask vacuum evaporation method for the purpose of preventing the protective layer from being formed on the leak electrode is not required. |
