Patent ID: 7518232

Claim:
A plasma display panel comprising: a first substrate; a second substrate spaced apart from the first substrate and facing the first substrate; an address electrode formed on the first substrate; a dielectric layer formed on the first substrate and covering the address electrode; a barrier rib formed on the dielectric layer; a discharge cell being formed in a space enclosed by the barrier rib, the first substrate, and the second substrate; a gas discharge being performed in the discharge cell; an inorganic adsorbent included in the barrier rib for absorbing an impurity generated in the discharge cell, the barrier rib including about 1 wt % to about 10 wt % of the inorganic adsorbent based on the total weight of the barrier rib; a phosphor layer formed inside the discharge cell; a display electrode formed on a surface of the second substrate facing the first substrate; a dielectric layer formed on the surface of the second substrate and covering the display electrode; and a protection layer formed on the dielectric layer of the second substrate.
