Abstract: A gas discharge panel on which a color image is displayed precisely and which is easy to manufacture. Between first and second substrates (11, 21) facing each other with an interval, a discharge space containing a discharge gas is formed. At least on one of the two substrates, pairs of electrodes (12a, 12b) for sustaining discharge are provided, and on the first substrate phosphor layers (24R, 24G, 24B) are formed, thus arranging discharge cells in a matrix along the electrode pairs. An image is displayed by selectively operating discharge cells. Between the first and second substrates, gap members (30) having predetermined shapes are disposed at portions corresponding to the boundaries among the discharge cells.

Abstract: A production device for a plasma display panel comprising a protection layer forming means for forming a dielectric protection layer on a first plate, a phosphor layer firing means for firing a phosphor layer spread on a second plate, a sealing means for sealing between the first plate surface formed with the dielectric protection layer and the second plate surface formed with the fired phosphor layer, the both surfaces being opposite to each other, and an exhausting/baking means for exhausting/baking a portion between the first plate and the second plate, wherein the above four means are disposed in at least one enclosed chamber, and the interiors of the enclosed chambers and portions between the at least one enclosed chambers are all kept in a gaseous atmosphere having a vapor partial pressure of up to 10 mPa or an atmospheric pressure of up to 1 Pa, whereby water absorbencies of the protection layer and the phosphor layer are restricted, lowering in PDP performance is prevented, and deterioration of the protection layer by carbon dioxide can be prevented due to the protection layer kept out of contact with carbon dioxide in the air.
