The reducing force in a float furnace is controlled to be decreased so that Sn++ content on a surface of the glass substrate forming an Ag electrode is a predetermined value or less. When the resultant Sncontent on the surface of the glass substrate forming the Ag electrode exceeds the predetermined value, the surface is partially removed to decrease the Sncontent to the predetermined value or less to suppress the occurrence of yellowing of the glass substrate.

An object of the present invention is to provide a technique for relatively easily suppressing the yellowing of a Plasma Display Panel in which electrodes comprising silver are disposed on the substrates, and thus render image displays with high luminance and high quality. In order to achieve the object, an arrangement is made in which the electrodes comprising silver further include an element whose standard electrode potential is lower than that of silver, such as Cr, Al, In, B, and Ti, or a compound of such an element, as a silver ionization inhibiting substance.

Plasma display panel with an improved electrode

A PDP has first and second substrates which face each other with a space in between. A display electrode pair and a dielectric layer are formed on the first substrate, and a plurality of discharge cells are formed between the first and second substrates along the display electrode pair. In this construction, two or more depressions are provided in the dielectric layer in an area corresponding to each discharge cell. This improves luminous intensity and illumination efficiency. Also, to form the dielectric layer on the first substrate, first a transfer film is made by providing a dielectric precursor layer on a support film, then depressions are formed in the dielectric precursor layer of the transfer film, and lastly the dielectric precursor layer of the transfer film is transferred onto the first substrate. This decreases the number of manufacturing steps and increases the yield, thereby reducing manufacturing costs.

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 &#x3bc;m; 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 (&#x2014;OCH) cellulose molecules. After dispersion a charge-removing material is added to the phosphor ink.
