Abstract
PURPOSE: To obtain a display panel with low driving voltage and excellent luminous efficiency by coating the electron emission material consisting of hexaboride on the surface of a cool cathode and sealing the gas containing rare gas, such as helium in the gas discharge element.
CONSTITUTION: The low voltage operating cool cathode 40 coats electron emission material LaB6 on a conductor thin plate with minute holes which are set to the dishcarge cell holes 21, for example, on both surfaces of the nickel plate 41 thickly. The intermediate sheet 20 is laminated on this cathode substrate 41 and the back plate 30 on the front plate 10 and on the back, respectively. These peripheral sections are sealed using vacuum adhesive, for example, glass frit, and contain one type of rare gas including helium, neon, and argon or their mixed gas inside. Since this permits the cathode voltage of each discharge cell to drop in a small degree, the scattering and consumption of the cathode material is reduced due to ion impact. As a result, the cell has a long lifetime.
