Abstract
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.
