Title:
MANUFACTURING METHOD OF FLUORESCENT MATERIAL, PLASMA DISPLAY PANEL DISPLAY DEVICE AND FLUORESCENT LAMP
Document Type and Number:
WIPO Patent Application WO/2001/029147
Kind Code:
A1
Abstract:
A plasma display panel display device which uses fluorescent material which emits visible light when it is excited by ultraviolet radiation and whose luminance is sufficiently high and hardly deteriorated. Small spherical particles which are obtained by a hydrothermal synthesis method are employed as the fluorescent material particles of which respective fluorescent material layers emitting red, green and blue lights are composed. Since the fluorescent material layers which have few oxygen defects causing luminance decline and luminance deterioration are formed, the display device whose luminance is sufficiently high and hardly deteriorated in comparison with those of a conventional device can be obtained.
