ABSTRACT:
It is aimed to provide a technique for easily suppressing swellings produced in end parts of partitions, thereby achieving a PDP capable of displaying a high-quality image.A PDP therefore has a plurality of partitions that include: (a) a plurality of main parts; and (b) a plurality of sub parts that each extend from an end part of one of the plurality of main parts parallel to a direction perpendicular to a direction in which the main parts extend. This allows each partition to have an end that is wider than a center part of the partition.In the process of forming PDP partitions, end parts of the partitions are partially heated, after they are baked, to a temperature higher than a softening point of a partition material. As a specific partial heating method, a method with which a laser beam is projected onto an end part is suitable.
