Title:
PLASMA DISPLAY PANEL AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/139183
Kind Code:
A1
Abstract:
This invention is directed to modification of a protective layer to solve both
problems of “discharge delay” and “temperature dependency
of discharge delay” while realizing good drive at low voltage. There
is also provided a plasma display panel, which can realize excellent display
properties, by solving the above problems and, further, suppressing “dependency
of discharge delay upon space charge”. An alkoxide of magnesium having
a purity of not less than 99.95% (Mg(OR)2) or acetylacetone of magnesium
having a purity of not less than 99.95% is provided. A small amount of acid is added
to this aqueous solution for hydrolysis to prepare a gel of magnesium hydroxide
as an MgO precursor. The gel is fired in the air at a temperature of 1500°C
or above to prepare a powder containing MgO fine particles (16a to 16d) having
an NaCl crystal structure surrounded by (100) face and (111) face. The powder
is coated on the dielectric layer (7) or surface layer (8) to form a group of MgO
fine particles (16).
