An electron-emitting source of this invention includes at least a carbon nanotube formed from a columnar graphite layer. Electron are emitted from the tip of the carbon nanotube.

Electron-emitting source and method of manufacturing the same

A display tube for a light source including a translucent face glass assembly having a front surface side which is formed spherically, a peripheral portion on which a step portion is formed, inner surface side on which a phosphor layer and a metallized film are sequentially formed, and a contact segment having one end connected to the metallized film. A glass bulb is provided having one open end portion sealed to the step portion of the translucent face glass assembly with low-melting frit glass. A stem assembly is provided having a anode electrode assembly and a cathode assembly mounted therein. The anode electrode assembly and the cathode assembly are accommodated in the glass bulb. The contact segment is contacted by the anode electrode assembly, the stem assembly being hermetically sealed at the other open end portion of the glass bulb. A high voltage applied to the anode assembly accommodated in the glass bulb is applied to the metallized film through the path of the contact segment.
