摘要：
Provided is a manufacturing method of a CNT emitter with density controlled CNT, comprising: (i) fabricating a CNT paste by dispersing a carbon nanotube (CNT) powder, two kinds or more of inorganic fillers which have a lower melting temperature than the CNT and different oxidation degrees of the CNT, and an organic binder in a solvent; (ii) coating the CNT paste on an electrode formed above a substrate; (iii) sintering the substrate coated with the CNT paste to selectively oxidize the CNT around one kind of inorganic filler among two kinds or more of the inorganic fillers; and (iv) treating the surface of the CNT paste so that the surface of the CNT paste is activated.
