PRODUCTION METHOD FOR PLASMA DISPLAY PANEL EXCELLENT IN LUMINOUS CHARACTERISTICS

摘要

A production method for a PDP operating with a high luminous efficiency and being satisfactory in color reproducibility, wherein, when forming a sealant layer (15) on the outer periphery portions of the opposite surfaces of a front panel sheet (10) and rear panel sheet (20) during a sealing process in a PDP production, projections (16) or recesses (17) are partly provided to form clearances (18) on the outer periphery portions, and the sealant layer (15) is heat-softened in a dry gas atmosphere, thereby minimizing the heat deterioration of a blue fluorescent layer (25) by releasing moisture to the outside from the inner space via the clearances (18).
