FIELD EMITTER EQUIPPED WITH CARBON NANOTUBE FILM, METHOD FOR MANUFACTURING THE SAME, AND FIELD EMISSION DISPLAY DEVICE

摘要

PURPOSE: Provided is a field emitter equipped with a carbon nanotube film with which a thin film transistor is used in manufacturing a field emission display device having high density of electricity and operating at low voltage. CONSTITUTION: A field emitter includes a substrate (8), a thin film transistor section formed on the substrate (8) and composed of a semiconductor layer (7), especially polycrystalline silicon layer, source electrode (3), drain electrode (4), and gate electrode (2), and a current discharge section composed of carbon nanotube films formed on the drain electrode (4) of the thin film transistor section. The structure of the thin film transistor section is among a plane, stacker, and counter stacker form. And the surface of the drain electrode (4) which the carbon nanotube film connects to includes transition metals like nickel or cobalt for the growth of the carbon nanotube or the drain electrode (4) is made of catalytic metals.
