US 6,646,374 B1 · Light emitting element with mutually confronting electrodes

Abstract

A light emitting element comprises a housing formed by allowing respective first principal surfaces of a rectangular upper housing member made of glass material and having a recess at a central portion on its first principal surface and a rectangular lower housing member 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 pressing under a pressure in a predetermined atmosphere; a cavity formed by the respective recesses in the housing and enclosed with at least one of a gas and a light emitting substance; and two lead wires confronted with each other with the cavity 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.

Dependent claims

A light emitting element comprising:

at least two confronting and thermally bonded glass plate members, at least one of said glass plate members having a plurality of cavities formed therein, said glass plate members being thermally bonded to each other;
at least one gas and/or at least one light emitting substance enclosed inside each of said cavities;
and
mutually confronting electrodes disposed in each of said cavities, said electrodes comprising lead wires in contact with each of said two confronting and thermally bonded glass plate members, said lead wires being interposed between said glass plate members and fixed onto a surface of one of said glass plate members at a position at which said glass plate members contact each other.
