Abstract:
An alternating current type surface-discharge plasma display panel comprising a facing pair of substrates and a plurality of ribs interposed between the substrates so as to form a plurality of spaces,the plurality of spaces being provided with a phosphor layer and filled with discharge gas, so as to form a plurality of discharge spaces; inside each of the discharge spaces, plural pairs of display electrodes covered by a dielectric layer being provided, the dielectric layer is made of two different sets of material, the plasma display panel performing displaying by the following steps: 1) writing by an accumulation of electric charge in the dielectric layer, 2) applying a predetermined sustaining voltage between the pairs of display electrodes, 3) glow-discharging in selected discharge spaces in which the electric charge has been accumulated in the dielectric layer, and 4) converting ultraviolet light resulting from the glow-discharge into visible light by means of the phosphor layer, wherein the dielectric layer is made by laminating the two different dielectric materials, and wherein the panel structure is set such that an equivalent electric field strength of 37 V/cmÂ·Pa or more is generated in the selected discharge spaces, when the predetermined sustaining voltage is applied.
