Abstract: A display device can realize the highly efficient electron emission characteristics by ensuring the exposure of carbon nanotubes 13 in the inside of a vacuum by fixing the carbon nanotubes 13 to cathode wires 12 such that the carbon nanotubes 13 are not easily removed from the cathode wires 12 with the small resistance which enables the carbon nanotubes 13 to have the enough electron emission ability. Some end portions or some intermediate portions of the carbon nanotubes 13 are embedded into the cathode wires 12 formed on a rear substrate 11 and, at the same time, contact points where the carbon nanotubes 13 cross each other or portions in the vicinity of the crossing portions are bonded to each other by bonding films 14.

Abstract: A field emission display device (1) includes a cathode plate (20), an electrically resistive buffer (30) made from carbon formed on the cathode plate, electron emitters (40) made from carbon formed on the buffer, and an anode plate (50) spaced from the electron emitters thereby defining an interspace region therebetween. Each electron emitter includes a nano-rod. The combined buffer and electron emitters has a gradient distribution of electrical resistivity such that highest electrical resistivity is nearest the cathode plate and lowest electrical resistivity is nearest the anode plate. When emitting voltage is applied between the cathode and anode plates, electrons emitted from the electron emitters traverse the interspace region and are received by the anode plate. Because of the gradient distribution of electrical resistivity, only a very low emitting voltage needs to be applied. Other embodiments include single walled and multi-walled nanotubes (40null, 40null).
