PLASMA DISPLAY DEVICE AND METHOD OF MANUFACTURING GREEN PHOSPHOR MATERIAL FOR PLASMA DISPLAY DEVICE

摘要

Provided is a plasma display device having a novel phosphor layer which emits green light and improved initial emission luminance and improved emission luminance maintaining rate. The phosphor layer includes a mixture of particles of Zn2SiO4:Mn and particles of (Y, Gd)BO3:Tb. The surface of the particles of Zn2SiO4:Mn is covered with aluminum oxide. The ratio of Al to Si measured by an X-ray photoelectron spectroscopy (XPS) apparatus on the particle surface is 0.6 or more but not more than 7.0.
