Abstract
A plasma display panel and the manufacturing method thereof. Forming partition wall structures on the back substrate of the paste display panel and forming the column-shaped protrusions at the positions corresponding to the cuts on the rib on the front substrate of the plasma display panel. The manufacturing process is simple and the alignment of the front and back substrate is easy. In addition, the size of the opening of the rib and the size of the cut can be easily adjusted according to the needs of the application during the manufacturing process.

A method of manufacturing a partition wall structure on a plasma display panel having a first substrate, a plurality of stripe electrodes parallel to a first direction formed on the first substrate, and an overcoat layer on the stripe electrodes and the first substrate, comprising:
- using pattern print to form grid-mesh-shaped shaping layer on the overcoat layer, the shaping layer includes a plurality of first stripe ribs and a plurality of second stripe ribs, 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, each of the third stripe ribs is formed on every first stripe layer, thereby forming partition wall structure.
A method of manufacturing a partition wall structure on a plasma display panel having a first substrate, a plurality of stripe electrodes parallel to a first direction formed on the first substrate, and an overcoat layer on the stripe electrodes and the first substrate, comprising:
- forming a shaping layer on the overcoat layer;
- forming a dry photoresist layer on the shaping layer;
- exposing the dry photoresist layer to form a shading mask on the shaping layer, the shading mask includes a plurality of first stripe ribs and a plurality of second stripe ribs, each of the first stripe ribs is parallel to the first direction and is on the shaping layer between every two stripe electrodes, each of the second stripe ribs is parallel to the second direction and is perpendicular to every first stripe rib, each of the second stripe ribs crossing the stripe electrodes, forming breaking ribs to expose the shaping layer;
- performing a sand blast process to remove the shaping layer exposed to the shading mask to expose the overcoat layer and form the partition wall structure;
- and
- leaving remaining shaping layer in each of the breaking ribs.
