A defoaming method for removing air bubbles from a curable resin material and a contact portion of the resin material with an irregular structure of a flat metallic mold. The mold includes a fine structural region having a fine irregular structure and a flat region in the periphery of the fine structural region. The curable resin material is applied to the irregular structure of the fine structural region, filling the irregular structure with the resin material.

Defoaming method, defoaming device and manufacturing method of transfer mold

To provide a flexible mold () useful for manufacturing a PDP rib having a lattice pattern and other microstructures, and capable of highly precisely manufacturing the microstructures without involving defects such as occurrence of bubbles and pattern deformation. A flexible mold () comprises a base layer () made of a first curable material having a viscosity of 3,000 to 100,000 cps at 10 to 80&#xb0; C. and a coating layer () coating a surface of the base layer () and made of a second curable material having a viscosity of 200 cps or below at 10 to 80&#xb0; C.

Flexible mold and method of manufacturing microstructure using the same

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.
