摘要： The object of the present invention is to provide a high-intensity, reliable plasma display panel even when the cell structure is fine by resolving the problems such as a low visible light transmittance and low voltage endurance of a dielectric glass layer. The object is realized by forming the dielectric glass layer in the manner given below. A glass paste including a glass powder is applied on the front glass substrate (11) or the back glass substrate (21), according to a screen printing method, a die coating method, a spray coating method, a spin coating method, or a blade coating method, on each of which electrodes have been formed, and the glass powder in the applied glass paste is fired. The average particle diameter of the glass powder is 0.1 to 1.5µm and the maximum particle diameter is equal to or smaller than three times the average particle diameter. Furthermore, 5-30wt% of TiO 2 is added to the glass powder in case the glass powder is included by a glass paste which is applied on the back glass substrate (21). By adding the TiO 2 , the dielectric glass layer (23) on the back glass substrate (21) reflects the light emitted from a phosphor (25) toward the front panel (10).

摘要： 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 5µm; 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 (-OC 2 H

摘要： A PDP with superior light-emitting characteristics and colour reproduction is achieved by setting the chromaticity coordinate y (the CIE colour specification) of light to 0.08 or less, more preferably 0.07 or less, or 0.06 or less, enabling the colour temperature of light to be set to 7,000K or more, and further to 8,000K or more, 9,000K or more or 10,000K or more. The PDP is manufactured by a method in which the processes for heating the fluorescent substances such as the fluorescent substance baking, sealing material temporary baking, bonding, and exhausting processes are performed in a dry gas atmosphere, or in an atmosphere in which a dry gas is circulated at a pressure lower than the atmospheric pressure. More particularly, the method comprises a preparative heating step for heating a front panel and a back panel in an atmosphere of dry gas while a space between the sides of the panels facing each other is opened, a fluorescent substance layer being formed on at least one of the front panel and the back panel, a sealing material layer being formed on at least one of the front panel and the back panel; and a bonding step for, after the preparative heating step, putting the front panel and the back panel together to form inner space between the panels, and bonding the front panel and the back panel by maintaining a bonding temperature equal to or higher than a softening point of the sealing material.
摘要翻译：通过将光的色度坐标y（CIE颜色规格）设定为0.08以下，更优选为0.07以下，或0.06以下，可以实现具有优异的发光特性和色彩再现的PDP，使得光的色温设定为7,000K以上，进一步为8,000K以上，9000K以上或10,000K以上。 PDP通过以下方法制造：在干燥气体气氛中或在干燥气体的气氛中进行荧光物质烘烤，密封材料暂时烘烤，粘合和排出处理等荧光物质的加热处理在低于大气压的压力下循环。在前面板和后面板被临时烘烤之后，当面板不被冷却到室温时开始粘合面板的过程，同时干燥气体在前面板和后面板之间的内部空间中循环。这减少了加热所需的时间和能量，从而降低制造成本。
