摘要

A method of producing a discharge display device enables formation of a satisfactory LaB6 cathode without using an LaB6 paste containing a glass binder. The method comprises applying a conductive paste containing a glass binder, temporarily drying the conductive paste to form a conductive paste layer (10), forming an LaB6 layer (11) containing no glass binder on the conductive paste layer (10), burning the conductive paste layer (10) and the LaB6 layer (11) at the same time, and activating the LaB6 layer (11) after it has been burnt, and after an exhausting step, by gas discharge with a large current to form an LaB6 cathode.
