Abstract

A full color three electrode surface discharge type plasma display device that has fine image elements and is large and has a bright display. The three primary color luminescent areas are arranged in the extending direction of the display electrode pairs in a successive manner and an image element is composed by the three unit luminescent areas defined by these three luminescent areas and address electrodes intersecting these three luminescent areas. Further, phosphors are coated not only on a substrate but also on the side walls of the barriers and on address electrodes. The manufacturing processes and operation methods of the above constructions are also disclosed.

Claims

1. A surface discharge type AC color plasma display panel rear substrate assembly, comprising:

a glass plate having a main surface;

plural address electrodes supported on the main surface of the glass plate in parallel relationship; and

plural barrier ribs supported on the main surface of the glass plate with a height substantially equal to a gap length of a given discharge space and arranged to divide said discharge space into cells, each of which cells corresponding to a position of a respective said address electrode, said barrier ribs having a flat top portion of a width not less than 7.5 μ

m and a bottom portion of a width wider than the top portion.

2. A surface discharge type AC color plasma display panel rear substrate assembly, comprising:

a glass plate having a main surface;

plural address electrodes supported on the main surface of the glass plate in parallel relationship;

plural barrier ribs, supported on the main surface of the glass plate with a height substantially equal to a gap length of a given discharge space-, and arranged to divide said discharge space into cells, each of which cells corresponds to a position of a respective said address electrodes, said barrier ribs having a flat top portion of a width not less than 7.5 μ

m and a bottom portion of a width wider than the top portion; and

plural color phosphor layers of different primary colors formed in respective, plural cells and arranged in a repeating succession corresponding to said address electrodes, said color phosphor layers affording a charge storable surface and covering the address electrodes.
