Patent ID: 7037159

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 plurality of stripe protrusions on the surface of the shaping layer, wherein each of the protrusions is on the shaping layer between every two stripe electrodes and is parallel to the first direction; forming a photoresist layer on the shaping layer; exposing the 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 formed on each of the stripe protrusions, each of the second stripe ribs is parallel to a second direction and is perpendicular to the first direction; and performing a sand blast process to remove the shaping layer exposed to the shading mask to expose the overcoat layer to form the partition wall structure.
