Abstract
An electrode for discharge light source which is suitable for discharge display on account of its high reliability and outstanding discharge characteristics attributable to the metal conductor which is formed 1-5 .mu.m thick in the discharge container and also to the film of the material for secondary emission which is formed on the metal conductor from a compound composed of LaB.sub.6 and Ba in an amount of 0.01-20 mol % of LaB.sub.6 or a compound composed of LaB.sub.6, Ba in an amount of 0.01-20 mol % of LaB.sub.6, and Ca in an amount of 0.01-5 mol % of Ba, and is 0.5-2 .mu.m thick so that it is free of pin-holes.
