Abstract

A plasma display panel includes a pair of substrates forming a discharge space between the substrates, and lateral barrier ribs extending in a row direction and longitudinal barrier ribs extending in a column direction that divide the discharge space into cells. Each lateral barrier rib is divided into two portions in the column direction such that a vent passage is formed in the divided portion. In the plasma display panel, raised portions, which are lower than the lateral barrier ribs and connect the lateral barrier ribs divided into the two portions with each other, are formed in the vent passage.

Claims (7)

1. A plasma display panel comprising:

a pair of substrates forming a discharge space between the substrates; and

lateral barrier ribs extending in a row direction and longitudinal barrier ribs extending in a column direction that divide the discharge space into cells, each lateral barrier rib being divided into two portions in the column direction such that a vent passage is formed in the divided portion, wherein

raised portions, which are lower than the lateral barrier ribs and connect the lateral barrier ribs divided into the two portions with each other, are formed in the vent passage; and

the raised portions are formed on a line connecting the centers of cell areas in the column direction.

2. The plasma display panel according to claim 1 , wherein the height of the raised portions is set to about half the height of the lateral barrier ribs.

3. The plasma display panel according to claim 1 , wherein the raised portions are formed at positions overlapping in a plane view with each of address electrodes formed on the substrate placed in the rear side of the pair of substrates.
