Patent ID: 6942535

Claim:
A method of manufacturing a partition wall structure on a plasma display panel, comprising the steps of: providing a substrate, with a plurality of stripe electrodes which form on the substrate, each of the stripe electrodes is parallel to a first direction; forming an overcoat layer on the stripe electrodes and the substrate; forming a shaping layer on the overcoat layer; forming a grid-mesh-shaped photo-sensing shading layer on the shaping layer, the photo-sensing shading layer includes a plurality of first stripe ribs and a plurality of second stripe ribs, each of the first stripe ribs is on the shaping 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, the height of the first stripe rib is larger than the height of the second stripe rib; exposing the photo-sensing shading layer to form a shading mask on the shaping layer; 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.
