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