Abstract

A plasma display panel (PDP) includes a first plate, and a second plate disposed to face the first plate via a discharge space and providing barrier ribs. A plurality of first electrodes and a plurality of second electrodes extending in a first direction, and a dielectric layer covering the first electrodes and the second electrodes are provided on the first plate. A plurality of address electrodes extending in a second direction, and a protective layer covering the dielectric layer and the address electrodes and exposing at least a part of the protective layer to the discharge space are provided on the dielectric layer. The address electrodes are made up by including a conductive layer formed by either one of aluminum and an alloy containing aluminum and copper and by not including a layer of a simple substance of copper.

Dependent claims

A plasma display panel, comprising:

a first plate;
a second plate disposed to face the first plate via a discharge space and providing barrier ribs;
a plurality of first electrodes and a plurality of second electrodes provided on the first plate, extending in a first direction, and disposed to have intervals with one another;
a dielectric layer provided on the first plate and covering the first electrodes and the second electrodes;
a plurality of address electrodes provided on the dielectric layer, extending in a second direction intersecting with the first direction, and disposed to have intervals with one another;
and
a protective layer provided on the dielectric layer, covering the dielectric layer and the address electrodes, and exposing at least a part of the protective layer to the discharge space, wherein
the address electrodes include a conductive layer formed by an alloy of aluminum and copper, the conductive layer not including a simple substance of copper.
