Verfahren zur Herstellung eines lichtemittierenden Elements

摘要

A light emitting element comprises a housing (34) formed by allowing respective first principal surfaces of a rectangular upper housing member (12) made of glass material and having a recess at a central portion on its first principal surface and a rectangular lower housing member (14) made of glass material and having a recess at a central portion on its first principal surface as well to make contact with each other so that they are thermally glued by press under a pressure in a predetermined atmosphere; a cavity (16) formed by the respective recesses (30, 32) in the housing (34) and enclosed with at least one of a gas and a light emitting substance; and two lead wires (18, 20) confronted with each other with the cavity (16) interposed therebetween. Accordingly, it is possible to simultaneously realize the integration and the miniaturization of the electronic tube and present the display expression for information transmission at a high brightness.
