Fluorescent layer forming apparatus

摘要

The present invention provides a fluorescent layer forming apparatus for applying a fluorescent material paste into a recess defined between barrier ribs formed on a substrate for formation of a fluorescent layer in a plasma display panel production process. The apparatus comprises: a nozzle for ejecting the fluorescent material paste; and a plurality of fine attachments provided at one end of the nozzle with distal end portions thereof being arranged in convergent relation. The fluorescent material paste is ejected along the plurality of fine attachments thereby to be applied into the recess without formation of a clot. Thus, the fluorescent layer can accurately be formed in the intended recess between the barrier ribs without adhesion of the fluorescent material paste onto the top edges of the barrier ribs.
