Plasma display panel
View Patent ↗A plasma display panel (PDP) is made of front panel ( 2 ) and a rear panel. The front panel includes display electrodes ( 6 ), dielectric layer ( 8 ), and protective layer ( 8 ) that are formed on front glass substrate ( 3 ). The rear panel includes electrodes, barrier ribs, and phosphor layers that are formed on a rear glass substrate. The front panel and the rear panel are faced with each other, and the peripheries thereof are sealed to form a discharge space therebetween. Display electrodes ( 6 ) includes metal electrodes ( 4 b , 5 b ) each containing at least silver and binding glass. The binding glass of black electrodes ( 41 b , 51 b ) and white electrodes ( 42 b , 52 b ) constituting metal bus electrodes ( 4 b , 5 b ) contains at least bismuth oxide and has a softening point exceeding 550° C.
1. A plasma display panel (PDP) comprising:
a front panel including display electrodes, a dielectric layer, and a protective layer that are formed on a glass substrate; and
a rear panel including address electrodes, barrier ribs, and phosphor layers that are formed on a substrate, wherein the front panel and the rear panel are faced with each other, and peripheries of the front panel and the rear panel being sealed to form a discharge space therebetween, wherein:
each of the display electrodes includes a metal electrode including a black electrode and a white electrode layered over the black electrode,
the white electrode includes at least silver and a first binding glass,
the first binding glass of the white electrode includes 20 wt% or more to less than 30 wt% of the bismuth oxide and includes 0.1 wt% to 7 wt% (inclusive) of at least one of molybdenum trioxide and tungstic trioxide therein and has a softening point exceeding 550° C., and
the black electrode contains a second binding glass and metallic fine particles or metallic oxide made of at least one element selected from a group consisting of iron (Fe), cobalt (Co), nickel (Ni), manganese (Mn), ruthenium (Ru), and rhodium (Rd).
