A PDP having excellent display quality is realized by realizing a back plate that does not contain lead, ensures shape accuracy and has high withstand voltage performance. A front plate on which a display electrode, a dielectric layer, and a protective layer are formed on a front glass substrate, an address electrode, a partition wall, and a phosphor layer are formed on the rear glass substrate. Is a PDP in which a discharge space 16 is formed by sealing the periphery of the back plate 10 and the base dielectric layer 13 is provided so as to cover the address electrodes 12. In addition, the barrier rib 14 is provided, and the underlying dielectric layer 13 is made of dielectric glass containing at least bismuth oxide and having a softening point temperature exceeding 550 ° C.
