PURPOSE:To form LaB6 cathode having strong bonding force by forming LaB6 layer containing no LaB6 onto temporarily dried conductive paste layer and burning simultaneously. CONSTITUTION:A trigger electrode 8 and a dielectric layer 7 are formed on a rear face glass substrate 3 then conductive paste containing glass binder such as Ni paste is printed onto the dielectric layer 7 to form Ni paste layer 10. Then LaB6 paste composed only of LaB6 fine powder and proper solvent is printed onto Ni paste layer 10 to form LaB6 paste layer 11 which is dried then Ni paste layer 10 and LaB6 paste layer 11 are burnt simultaneously. Thereafter, the surface 11'b of LaB6 layer 11' not impregnated with glass binder is removed. Then frit seal, thermal exhaust, encapsulation of required gas and final encapsulation are performed to apply predetermined voltage between the anode and Ni underlying electrode 10' thus to perform activation through high current gas discharge. |
