    • 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.
    • 本发明的目的是提供一种气体放电面板,其中放电能量转换成可见光的转换效率和面板亮度得到改善,色纯度尽可能地得到改善。 为了达到这个目的,在气体放电面板中,放电气体的压力设定在比常规气体压力高的800-4000乇的范围内。 此外,使用包含氦,氖,氙和氩的稀有气体混合物作为放电气体,而不是传统的放电气体。 这里,优选Xe的比例为5体积%以下,Ar为0.5体积%以下,He为55体积%以下。 利用这种稀有气体混合物,随着点火电压的抑制,发光效率提高。 此外,显示电极和寻址电极布置在前盖板和背板之一的表面上,在显示电极和寻址电极之间存在电介质层。 利用这种结构,即使气体压力高,也以相对低的电压进行寻址。
