ELECTRIC FIELD EMISSION ELEMENT USING CARBON NANO TUBE

摘要

PURPOSE: An electric field emission element using a carbon nano tube is provided to embody a display element of an high image quality/high efficiency by applying for a display element using a CNT. CONSTITUTION: A cathode(26) and a gate electrode(28) are formed at the upper surface of the lower substrate(24). A CNT emitter(30) catches the cathode(26). A protecting layer(32) is formed on the surface of the lower substrate(24). An anode(36) and a fluorescence substance(38) are successively laminated at the upper and lower plane of the upper substrate(34). The CNT emitter(30) is arranged in a conductive epoxy(42) in a plane direction. A gate electrode(28) is position at between the cathode(26) in a predetermined interval and the CNT emitter(30). The CNT emitter(30) emits an electron by the voltage applying between the gate electrodes(28). The emitted electron is accelerated by the voltage applying the anode(36), and then collided with the fluorescence substance(38).
