Abstract: An improvement of a phosphor layer in mainly the luminance and chromaticity of plasma displays by using phosphor particles which are platy or have an appropriate particle diameter distribution to thereby increase the percentage of loading with the phosphor particles. In an aluminate phosphor containing barium as a base material and europium as an activator, the amount of europium serving as a luminescence center is controlled by using base materials in an appropriate proportion, and heat resistance is improved by appropriately regulating the amount of europium replacement, and durability is improved by appropriately regulating the amount of strontium replacement.

Abstract: A PDP is characterized in that a dielectric layer is made of a glass containing at least ZnO and 10 wt% or less of R2O (where R is one of Li, Na, K, Rb, Cs, Cu, and Ag) and not containing PbO and Bi2O3, the product of the dielectric constant ε multiplied by the loss factor tan δ is 0.12 or less. Therefore, the problem that the components such as Ag and Cu of a display electrode diffuse into the dielectric layer to form colloidal particles, which mar the display performance of the display is effectively overcome. The product of the dielectric constant ε multiplied by the loss factor tan δ is smaller than conventional, and hence the PDP has a lowered power consumption. The glass having the composition has a softening point of 60° or less lower than conventional, and therefore the production cost such as for baking the dielectric layer is lowered.

Abstract translation: PDP的特征在于，电介质层由至少包含ZnO和10重量％以下的R 2 O（其中R为Li，Na，K，Rb，Cs，Cu和Ag中的一种）且不含有 PbO和Bi2O3，介电常数ε乘以损耗因子tanδ的乘积是0.12或更小。 因此，有效地克服了显示电极的Ag，Cu等成分扩散到电介质层中而形成胶体粒子的问题，有效地克服了显示器的显示性能。 介电常数ε乘以损耗因子tanδ的乘积小于传统，因此PDP具有较低的功耗。 具有该组成的玻璃的软化点比传统的低60°或更低，因此诸如烘烤介电层的生产成本降低。

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 mu 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 (-OC2H
