| Zusammenfassung: | The present invention discloses a method of producing a discharge display device which enables formation of a satisfactory LaB6 cathode without using a LaB6 paste containing a glass binder. The method of the present invention comprises the steps of applying a conductive paste containing a glass binder, temporarily drying said conductive paste to form a conductive paste layer, forming a LaB6 layer containing no glass binder on said conductive paste layer, burning said conductive paste layer and said LaB6 layer, at the same time, and activating said LaB6 layer after being burnt, and after an exhausting step by gas discharge with large current to form a LaB6 cathode. |
