Abstract
A plasma display panel includes a front panel including a glass substrate, a display electrode formed thereon, a dielectric layer formed so as to cover the display electrode, and a protective layer formed on the dielectric layer; and a rear panel disposed facing the front panel so that discharge space is formed and including an address electrode formed in a direction intersecting the display electrode, and a barrier rib for partitioning the discharge space. The dielectric layer of the front panel contains bismuth oxide and calcium oxide without containing lead, and does not contain lead. The protective layer on the dielectric layer is formed by forming a base film on the second dielectric layer and attaching a plurality of crystal particles made of metal oxide to the base film so as to be distributed over an entire surface of the base film.
