Patent ID: 7423378

Claim:
A plasma display panel (PDP), comprising: a first substrate; at least one electrode arranged on the first substrate; a plurality of first barrier formed on the first substrate; a plurality of second barrier ribs formed on the first substrate and substantially perpendicular to the plurality of first barrier ribs such that the plurality of first and second barrier ribs form lattice shaped barrier ribs; a phosphor layer formed over the at least one electrode formed on the first substrate; a second substrate; a pair of electrodes comprising a first electrode and a second electrode formed on the second substrate; and a dielectric formed over the first and second electrodes, wherein at least one groove or at least one recess is formed in the dielectric layer on each side of the pair of electrodes such that the dielectric layer includes one or more protruding portions, wherein each protruding portion covers both electrodes of the pair of electrodes and extends between the grooves or recesses, and wherein a width of the at least one groove or the at least one recess is larger than a width of at least one of the plurality of first barrier ribs or at least one of the plurality of second barrier ribs.
