Plasma display panel including barrier ribs and method for manufacturing barrier ribs

A plasma display panel, comprising:

• a first substrate and a second substrate that are substantially parallel and have a predetermined gap therebetween;
• a plurality of address electrodes formed on a surface of the first substrate opposing the second substrate, the address electrodes being provided in a line pattern and substantially in parallel with each other;
• a dielectric layer formed over a surface of the first substrate covering the address electrodes;
• barrier ribs formed on the dielectric layer in a lattice pattern, the barrier ribs defining discharge cells;
• a plurality of discharge sustain electrodes formed on a surface of the second substrate which opposes the first substrate, the discharge sustain electrodes being formed in a line pattern in a direction substantially perpendicular to the address electrodes;
• and
• a transparent dielectric layer and a protection layer formed over the surface of the second substrate covering the discharge sustain electrodes,
• wherein the barrier ribs include a plurality of first barrier rib members formed in a stripe pattern perpendicular to a direction of the address electrodes, and a plurality of second barrier rib members formed within a space between two neighboring first barrier rib members, the barrier rib members defining the discharge cells to be arranged in a zigzag manner along a same direction as the address electrodes, and
• wherein at least one of the first barrier rib members and the second barrier rib members is made of a non-transparent material.

A method for manufacturing barrier ribs for a plasma display panel, comprising:

• preparing a first substrate having address electrodes and a dielectric layer formed thereon, and printing a first insulating paste over a surface of the dielectric layer and forming a lower barrier rib member of a first predetermined height;
• printing a second insulating paste on the lower barrier rib member in a line pattern, and forming upper barrier rib members having a second predetermined height from a surface of the dielectric layer;
• coating a dry film resistor over a surface of the first substrate, fully covering the lower barrier rib member and the upper barrier rib members;
• positioning a photo mask, which has a lattice-shaped light passage pattern, over an entire surface of the dry film resist, then performing exposure through the light passage pattern to pattern the dry film resist such that the dry film resist covers all of the upper barrier rib members and part of the lower barrier rib member;
• and
• spraying sand at a high speed onto the surface of the first substrate such that exposed portions of the lower barrier rib member are removed, after which the dry film resist remaining on the first substrate is removed,
• wherein either or both the first insulating layer paste and the second insulating layer paste are made of non-transparent material.
