Abstract
A barrier rib structure for a plasma display panel is described. The barrier rib structure formed on a back substrate has a plurality of parallel barrier ribs. Each barrier rib has a plurality of nodes composed of two side-expanded trapezoid bulges. The barrier ribs are arranged according to the nodes to form a plurality of discharge spaces between the barrier ribs and a plurality of gas channels between the nodes to connect the discharge space.

A barrier rib structure for a plasma display panel formed on a back substrate, comprising:
- a plurality of barrier ribs on said back substrate, each of said barrier ribs having a plurality of wide portions, each of said wide portions being composed of two protrudent trapezoid bulges, said barrier ribs being arranged parallel to each other with said wide portions lined up to form a plurality of discharge spaces between said barrier ribs and a plurality of gas channels between said wide portions;
- and
- a mid-channel in said wide portion perpendicular to and connected to said gas channels adjacent to said wide portion.
A gas discharge luminescent structure of a plasma display panel, comprising:
- a first dielectric layer having a plurality of parallel address electrodes therein;
- a plurality of barrier ribs on said first dielectric layer respectively located between said address electrodes, each of said barrier ribs having a plurality of wide portions, each of said wide portions be composed of two protrudent trapezoid bulges, said barrier ribs being parallel to each other with said wide portions lined up to form a plurality of discharge space between said barrier ribs and a plurality of gas channels between said wide portions;
- a mid-channel in said wide portion perpendicular to and connected to said gas channels adjacent to said wide portion;
- a fluorescent layer on the sidewalls and bottom of said discharge space;
- and
- a second dielectric layer on said barrier ribs, said second dielectric layer having a plurality of parallel transparent electrodes therein, and said transparent electrodes crossing said address electrodes over said discharge space.
