Patent ID: 7361072

Claim:
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: using pattern print to form a grid-mesh-shaped shaping layer on the overcoat layer, the shaping layer includes the plurality of first stripe ribs and the plurality of second stripe ribs, wherein each of the first stripe ribs is on the overcoat layer between every two stripe electrodes and is parallel to the first direction, each of the second stripe ribs is parallel to a second direction, and is perpendicular to the first direction; and using pattern print to form a plurality of third stripe ribs on the shaping layer, wherein each of the third stripe ribs is formed on every first stripe rib, thereby forming the partition wall structure; 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.
