Abstract:
The present invention intends to provide a manufacturing method for a PDP that can continuously apply phosphor ink for a long time and can accurately and evenly produce phosphor layers even when the cell construction is very fine. To do so, phosphor ink is continuously expelled from a nozzle while the nozzle moves relative to channels between partition walls formed on a plate so as to scan and apply phosphor ink to the channels. While doing so the path taken by the nozzle within each channel between a pair of partition walls is adjusted based on position information for the channel. When phosphor particles is successively applied to a plurality of channels, phosphor ink is continuously expelled from the nozzle even when the nozzle is positioned away from the channels. The phosphor ink is composed of: phosphor particles that have an average particle diameter of 0.5 to 5 μm; a mixed solvent in which materials selected from a group consisting of terpineol, butyl carbitol acetate, butyl carbitol, pentandiol, and limonene are mixed; and a binder that is an ethylene group polymer or ethyl cellulose containing at least 49% of ethoxy group (—OC2H5) cellulose molecules. After dispersion a charge-removing material is added to the phosphor ink.
