Abstract:
1. A method of manufacturing a plasma display panel comprising: providing a first substrate; forming a plurality of stripe electrodes on the first substrate, wherein each of the stripe electrodes is parallel to a first direction; forming an overcoat layer on the stripe electrodes and the first substrate; providing a second substrate having an air-pump hole, parallel to the first substrate, forming a discharging space between the first substrate and the second substrate, wherein the discharging space connects to the air-pump hole; forming a partition wall structure on the first substrate, wherein the partition wall structure includes a plurality of first stripe ribs defining the discharging space to become a plurality of row discharging space, a plurality of second stripe ribs crossing the plurality of the first stripe ribs, each of the second stripe ribs has a cut in the row discharging space so that gas can flow through the row discharging space through the cut, the partition wall structure is formed by the steps of: forming a plurality of column-shaped protrusions on the second substrate, wherein the column-shaped protrusions are formed at positions corresponding to the cuts on the first substrate, the column-shaped protrusions on the second substrate embed into the cuts on the first substrate when the first substrate seals to the second substrate to leave a channel in the cut so that gas can flow through the row discharging space through the channel; sealing the edge of the first substrate and the edge of the second substrate to conceal the discharging space; and pumping air out of the discharging space through the air-pump hole, so that the gas in the row discharging space is pumped out from the air-pump hole through the cut.
