摘要： The object of the present invention is to provide a gas discharge panel, where the conversion efficiency of discharge energy into visible rays and the panel brightness are improved, with the color purity being improved as far as possible. To achieve this object, in a gas discharge panel, the pressure of discharge gas is set in a range of 800-4000 Torr, that is higher than a conventional gas pressure. Also, a rare gas mixture including helium, neon, xenon, and argon is used as discharge gas charged into discharge spaces, instead of conventional discharge gas. Here, it is preferable that the proportion of Xe is set to 5% by volume or less, that of Ar 0.5% by volume or less, and that of He under 55% by volume. With this rare gas mixture, the light-emission efficiency is improved, with the firing voltage being suppressed. Furthermore, display electrodes and address electrodes are arranged on the surface of either of a front cover plate and a back plate, with a dielectric layer existing between the display electrodes and the address electrodes. With this construction, addressing is performed with a relatively low voltage even if the gas pressure is high.

摘要： The object of the present invention is to greatly improve PDPs in luminance and luminous efficiency, compared to conventional PDPs. In order to achieve the object, the panel structure is set such that an equivalent field strength of at least 37V/cm·KPa is generated in selected discharge spaces in which the electric charge has been accumulated on their dielectric layer, when a discharge sustaining voltage is applied between a pair of display electrodes. To achieve such a high equivalent field strength as 37V/cm·KPa, adequate setting of the following factors of the panel structure is effective: a gap between a pair of display electrodes, a thickness and a permittivity of a dielectric layer, and an amount of Xe filled in discharge spaces.

摘要： A discharge panel capable of high-quality display by preventing erroneous discharge between adjacent lines in a sustaining electrode or the like. A sectional shape in a direction orthogonal to the longitudinal directions of both a first display electrode (101a) and a second display electrode (101b) has a stepped shape, a film thickness of a discharge gap (Gap1) side portion is greater than that on a non-discharge gap side, the film thickness of the respective steps being specified as L1, L2, L3 (L1>L2>L3). Accordingly, a discharge start voltage on the discharge gap side is lower than that on the non-discharge gap side even when the discharge gap and the non-discharge gap have the same width geometrically, thereby reducing erroneous discharge between adjacent cells positioned on an adjacent lines.

摘要： A surface-discharge type display device is provided that can reduce power consumption during sustain discharge and suppress the occurrence of illumination failures. A display electrode and a display scan electrode are aligned on a substrate, and a dielectric layer is formed on the substrate so as to cover the display electrode and the display scan electrode. An area having a lower relative permittivity than the dielectric layer is formed in an area surrounded on three sides by the display electrode, the display scan electrode, and the substrate. The dielectric layer allows sufficient wall charges for surface discharge to be accumulated, whereas the lower relative permittivity area allows the capacitance between the display electrode and the display scan electrode to be decreased. Accordingly, the power consumption during sustain discharge is reduced without causing illumination failures.

摘要： A PDP does not suffer from dielectric breakdown even though a dielectric layer is thin, with the problems of conventional PDPs, such as cracks appearing in the glass substrates during the production of the PDP being avoided. To do so, the surface of silver electrodes of the PDP is coated with a 0.1-10 &mgr;m layer of a metallic oxide, on whose surface OH groups exist, such as ZnO, ZrO2, MgO, TiO2, Al2O3, and Cr2O3. The metallic oxide layer is then coated with the dielectric layer. It is preferable to form the metallic oxide layer with the CVD method. The surface of a metallic electrode can be coated with a metallic oxide, which is then coated with a dielectric layer. The dielectric layer can be made of a metallic oxide with a vacuum process method or the plasma thermal spraying method. The dielectric layer formed on electrodes with the CVD method is remarkably thin and flawless. When the dielectric layer is formed with the vacuum process method or the plasma spraying method, warping and cracks conventionally caused by baking the dielectric layer are prevented. Here, borosilicate glass including 6.5% or less by weight of alkali can be used as the glass substrate.
