Patent ID: 8378572

Claim:
A plasma display panel, comprising: a front plate including a plurality of display electrodes, a first dielectric layer covering the plurality of display electrodes, and a protective layer covering the first dielectric layer; a rear plate including a plurality of address electrodes, a second dielectric layer covering the plurality of address electrodes, and barrier ribs disposed on the second dielectric layer, the barrier ribs including a first barrier rib arranged in a direction intersecting the plurality of display electrodes and a second barrier rib orthogonal to the first barrier rib; a sealing member configured to seal a peripheral edge of the front plate and a peripheral edge of the rear plate together; and a bonding layer disposed on the barrier ribs so that at least a portion of the bonding layer directly contacts the protective layer, and being configured to bond at least part of the barrier ribs and the front plate to each other, wherein the sealing member has a first glass member, the bonding layer has a second glass member, and a deformation point of the second glass member is lower than a softening point of the first glass member, and a softening point of the second glass member is higher than the softening point of the first glass member where in the second glass member includes Bi 2 O 3 and B 2 O 3 , and a molar ratio of Bi 2 O 3 to B 2 O 3 in the second glass member is not less than 0.25:1 and not more than 4:1.
