Patent ID: 8025543

Claim:
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 second stripe rib, wherein each of the first stripe ribs is parallel to the first direction and is on the shaping layer between every two stripe electrodes, the second stripe rib aligns along a second direction and is perpendicular to every first stripe rib, the second stripe rib crossing the stripe electrodes and having breaking cuts to expose the shaping layer, each breaking cut is between two adjacent first stripe ribs and a width of the breaking cut is smaller than a distance between two adjacent first stripe ribs; 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 cuts after the sand blast process.
