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.
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.
