Abstract: PROBLEM TO BE SOLVED: To solve the problem of a plasma display panel due to the fact that residual resist in forming a partition generates impurity gas in the panel, resulting in lower discharge efficiency. SOLUTION: The resist removing performance is improved by applying a ultraviolet ray before a partition is embedded. Thus, residual resist remaining in the plasma display panel and generation of impurity gas are eliminated to prevent lowering of discharge efficiency.

Abstract: PROBLEM TO BE SOLVED: To firmly join a pair of panel boards by forming and holding a paste joint material surface on a joining holding member, contacting an approximately whole apex of a plurality of barrier ribs of one side of the pair of panel boards to a surface of the joint material while controlling a degree of contact to attach the joint material, and joining the pair of panel boards oppositely to each other through the joint material. SOLUTION: A rear surface of a back panel PA2 having barrier ribs 18 and a fluorescent material layer on its surface, is sucked to a base 42 vertically slidable in parallel with a flat plate 41 having a flat joint material layer 40 of a paste joint material Ba having comparatively high viscosity and including the glass of a low melting point, whereby the curving of a back glass board is straightened. Partition upper surface parts 18a and a surface of the joint material layer 40 are contacted by the gentle movement of the base 42, and then separated in the opposite direction, which prevents the uneven coating and the elimination of the joint material Bd caused by the inertia force. The coating material Ba attached by surface tension is ideally coated in a state that it is thick at a central part and thin at a peripheral part in the direction perpendicular to the extending direction of the barrier ribs 18 acting as spacers in the joining.

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method capable of stably manufacturing a gas discharge panel wherein the apex parts of barrier ribs are entirely tightly fitted to a panel substrate in manufacturing the gas discharge panel such as a PDP. SOLUTION: When an envelope 40 of a PDP is formed and thereafter entered into a heating furnace 51, and a process for sealing the circumferential parts of both panels 10, 20 together by the use of a sealing material is carried out, the process is carried out while adjusting the pressure so as to set the internal pressure of the envelope 40 lower than the external pressure thereof. The pressure adjustment is carried out, for instance, by exhausting gas inside the envelope 40 through a piping member 26 by a vacuum pump 52. Thereby, both panels are sealed in a form pressed from the outside, so that the apex parts of barrier ribs and the front panel 10 are sealed in a form entirely tightly fitted together.
