Abstract
An apparatus is provided for producing a substrate for PDP, which can easily reduce ununiformity of a dielectric layer and defects of ribs. The apparatus is so constituted that it comprises: a table for the plate, a rib precursor supplying portion for providing a precusor of the ribs on the plate, a pliable mold having at least groove portions provided in parallel with each other at a fixed distance, which is disposed on the precursor of the ribs provided on the plate, a mold pressing portion for applying a pressure to the mold, thereby to contact the mold closely with the plate via the precursor of the ribs, and a driving portion for moving the mold pressing portion along the groove portions of the mold.
