Method of manufacturing soft mold to shape barrier rib, method of manufacturing barrier rib and lower panel, and plasma display panel

A method of manufacturing a barrier rib of a plasma display panel, the method comprising:

• preparing a mold to shape a barrier rib, the mold having a patterned surface;
• and
• pressing a dielectric sheet against the patterned surface of the mold to form a patterned first surface and an unpatterned opposing second surface on the dielectric sheet.

A method of manufacturing a lower panel of a plasma display panel, the method comprising:

• preparing a mold to shape a barrier rib, the mold having a pattern on a surface thereof;
• pressing a dielectric sheet into the mold, such that the dielectric sheet has a patterned first surface having projections that form a barrier rib pattern, and an opposing substantially flat second surface,
• pressure bonding the second surface of the dielectric sheet to a substrate, to cover electrodes disposed on a surface of the substrate.
