PURPOSE: The cathode of a discharge display tube in which the vapor of metal-like Hg and CS and gases like rare gases and H2 or their mixture are sealed is formed by a thermion-releasing substance, so that the discharge voltage can be greatly lowered and the low-voltage and low-power driving of the discharge display tube is made possible.
