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 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.

摘要： A gas discharge panel in which cell filled with a discharge gas are arranged as a matrix between a pair of opposed plates, and in which a pair of display electrodes on a surface of one of the pair of opposed plates extend across a plurality of cells in the direction of rows, where a gap between the pair of display electrodes has two discharge gap widths one of which is larger than the other. The voltage is lowered and the power consumption is properly restricted by starting the discharge at the discharge gap at a space having the smaller gap width. An excellent discharge efficiency is secured by sustaining the discharge at a space having the larger gap width.

摘要： In a plasma display panel, a partition wall defining a discharge space is formed of a thermal-sprayed film formed by thermal spraying of a partition wall material. A process for forming such a partition wall includes the steps of forming a photosensitive coating layer on a substrate; forming an opening having a prescribed pattern in the photosensitive coating layer; depositing the partition wall material to a prescribed height at least inside the opening by a thermal spraying technique, thereby forming the thermal-sprayed film; removing a portion of the thermal-sprayed film bulging out from a surface of the photosensitive coating layer by polishing; and removing the photosensitive coating layer to obtain the partition wall having a prescribed shape.
