Patent ID: 7151343

Claim:
A plasma display panel comprising: a first electrode and a second electrode parallel with each other on a first substrate, and covered with a first dielectric layer ( 4 ); a third electrode on a second substrate in a direction orthogonal to the first electrode and the second electrode, the second substrate facing the first substrate with a discharge space therebetween; a fourth electrode on the second substrate parallel to the first electrode and the second electrode, and covered with a second dielectric layer ( 16 ); and a first discharge space and a second discharge space on the second substrate partitioned apart by a barrier rib; a main discharge cell for performing a discharge with the first electrode, the second electrode and the third electrode, in the first discharge space, and a priming discharge cell for performing a discharge with the fourth electrode and at least one of the first electrode and the second electrode, in the second discharge space, wherein the plasma display panel is configured so that a thickness of the first dielectric layer ( 4 ) is thinner where there is a trench ( 5 ) over second discharge space ( 13 ) than a thickness of the first dielectric layer ( 4 ) in the first discharge space ( 11 ).
