An AC plane discharge plasma display panel having a first substrate section with an image display surface and a second substrate section opposed thereto, for displaying a desired image by means of gas electric discharge in discharge cells formed between the first and second substrate sections, wherein the first substrate section includes a glass substrate containing sodium oxide, an insulating film of SiO2 formed on the glass substrate by a dry film-forming method and having a thickness of more than about 100 nm, transparent electrodes, bus electrodes, pairs of discharge-sustaining electrodes formed on the insulating film, a dielectric layer formed on the insulating film in such a way as to cover the pairs of discharge-sustaining electrodes, and a cathode film formed on the dielectric layer. Therefore, even in such a display panel, the alkali barrier effect is maintained for a long time, and the progress of migration is suppressed, realizing an AC plane discharge PDP having a good durability.
