MANUFACTURING METHOD OF EMBEDDED TYPE SOFT MOLD FOR FORMING BULKHEAD OF PLASMA DISPLAY PANEL AND FORMING METHOD OF BULKHEAD UTILIZING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an embedded type soft mold for forming a bulkhead of a plasma display panel in which warping or break of the substrate is prevented and uniformity of the bulkheads is secured and separation of the soft mold after formation of the bulkheads is easy, and a bulkhead forming method utilizing the same. SOLUTION: The manufacturing method comprises a process for applying a photoresist on the surface of the basic mold frame substrate, a process in which a photoresist pattern is formed on the above applied photoresist using a photo mask formed with a bulkhead pattern and the basic mold frame is formed by exposure and development, a process in which liquid rubber material is filled in the basic mold frame, a process for hardening the rubber material, a process for separating the hardened rubber material from the basic mold frame, and a process in which the back face of the separated rubber material is ground and a through hole for determining the shape of the bulkhead is formed.
