Abstract

The invention provides a phosphor paste. The hosphor powder evenly and stably disperses over the paste and the time variation of viscosity is small, and the chromaticity variation of phosphor layer is small after burning. The phosphor paste contains phosphor powder, binder resin, primary amine or secondary amine compound with hydroxyl group, and / or an alkoxyl group and with molecular weight of below 300, and an organic solvent.

Description

technical field

[0001] The present invention relates to a phosphor paste formed by uniformly dispersing phosphor powder, in particular to a phosphor paste used in a plasma display panel (hereinafter referred to as PDP) and a method for manufacturing the display. Background technique

[0002] Compared with liquid crystal panels, PDPs can display at high speed and can be easily enlarged, so they are beginning to be applied to fields such as OA equipment and bulletin display devices. Furthermore, progress in the field of high-quality televisions and the like is also highly anticipated. With the expansion of the above-mentioned application range, a color PDP having a plurality of fine display units has gradually attracted attention.

[0003] The PDP generates plasma discharge between electrodes in a discharge space disposed between a front glass substrate and a rear glass substrate, and ultraviolet light generated from a gas enclosed in the discharge space causes phosphors in t...
