An intermediate electrode is formed in a space between an X display electrode and a Y display electrode parallel thereto. A negative voltage is applied to the Y display electrode to use the Y display electrode as a cathode. A charge is stored between the Y display electrode and an intermediate electrode to create an electric field. Upon the increase of the intensity of the electric field to a sufficiently high level, an instant discharge occurs between the Y display electrode and the X display electrode and intense ultraviolet rays are produced. The fluorescent layer excited by the ultraviolet rays emits visible light. Only a narrow pulse current flows through the X display electrode and the Y display electrode, so that power consumption can be suppressed at high emission efficiency.

Almost only choice by a secondary electron emission layer / protection layer covering the dielectric layer of an AC type PDP has been magnesium oxide (MgO) that is unstable during the production process and difficult to form, thus posing a serious production problem. An AC type PDP constructed such that, instead of covering the surface of a dielectric layer with a dielectric material such as MgO, an insular electrode is made by forming a conductive material such as nickel, aluminum, magnesium and lanthanum hexaboride into an insular shape, and the insular electrode is allowed to capacity-couple with a lower-layer bus electrode by means of an electrostatic capacity formed by a dielectric layer to operate the insular electrode as a sustained electrode.

A plasma display panel with reinforcing electrodes arranged at both ends of discharge cells along a direction address electrodes are formed and coupled to display electrodes. The reinforcing electrodes may comprise carbon-based material such as carbon nanotubes or graphite, and they may be stacked in two or more layers and covered with a dielectric layer and a protective layer. The dielectric layer may be interposed between the reinforcing electrodes and the display electrodes. The dielectric layer may expose the reinforcing electrodes so that the protective layer covers the reinforcing electrodes. A portion of the protective layer corresponding to the reinforcing electrodes has a surface roughness of about 300 nm to about 700 nm.

An AC type plasma display panel includes a plurality of pairs of display electrodes 12a and 12b, dielectric layer 15, a data electrode and float electrode 41. A pair of the plurality of pairs of display electrodes 12a and 12b are disposed parallel to each other on front substrate 10 and form a discharge gap for emitting light for display. Dielectric layer 15 is formed on front substrate 10 and covers the plurality of pairs of display electrodes 12a and 12b excluding at least a part of the discharge gap. The data electrode is disposed on a rear substrate, which is placed facing the front substrate across discharge space, in a manner to cross under the display electrodes. Float electrode 41 is disposed at the discharge gap on front substrate 10.

There is provided a PDP and an image display apparatus equipped with the same, in which the deterioration in the address discharge timelag with age is suppressed, which is bright, has guaranteed life, can stably be driven, is of low power consumption, high definition, and high image quality. There is provided a pair of sustaining discharge electrodes on the front substrate extending in a row direction for forming a display line, a floating electrode not connected to an external electrode is arranged on the same substrate as the pair of sustaining discharge electrode so as not to pass through a center line extending in a column direction and dividing the discharge cell into two equal parts, thereby intensifying the local potential of an area of the MgO surface not influenced by the sputtering by the sustaining discharge in the address discharge, promoting the electron emission from this area, and suppressing the deterioration of the address discharge timelag.

The invention discloses a novel microplasma device containing a floating electrode. An aluminum foil is adopted in the device as a material base; dense array micro-cavities are arranged on the aluminum foil; the inner part of each micro-cavity is provided with an alumina layer as a medium layer so that a basic Al / Al2O3 / Al coplanar electrode structure can be formed; both ends of each micro-cavity are relatively larger than the middle part in size; alumina exists only between both ends of each micro-cavity; pure aluminum remains between adjacent micro-cavities as the floating electrode so that an integral micro-cavity array is formed; simultaneously the two partial aluminum foil bases insulated at the upper and the lower sides of each micro-cavity are used as the electrodes of the device; after the upper and the lower electrodes are guided out, the whole base is sealed and vacuumized with glass so as to obtain the final novel microplasma device containing the floating electrode. The device is simple in structure and convenient to manufacture, can reduce the minimum sustaining voltage of discharging, and the luminescent efficiency is improved.
