PURPOSE:To obtain a display panel with a high luminance and little luminance deterioration by using a material with a good reflectance of ultraviolet rays and a material resistant to be oxidized under heat during the panel production and reluctant to spatter for a cathode and by using Al satisfying both requirements as an electrode material. CONSTITUTION:A power introduction terminal 2, lead wire 3, cathode 4, anode 5, reset electrode 6, and a pair of keep-alive electrodes 7 are provided on an insulation substrate 1 made of soda glass, etc., and they are covered with a cover glass 8 except for indidual electrodes. The discharge electrodes of these cathode 4, anode 5, etc. are formed by printing and burning Al paste. The surface of the Al cathode is silver-white and lustrous, therefore, the surface reflectance becomes large and the reflected light on the Al face can be utilized, furthermore, the ultraviolet rays generated by gas discharge are also reflected, thus the phophor can be efficiently energized. Accordingly, a display panel with a high luminance and little luminance deterioration can be available. |
