摘要
PROBLEM TO BE SOLVED: To provide a CNT film which can ensure mechanical film strength without depending on only an organic binder, easily achieves a flat shape, does not include bubbles therein, eliminates such a complicated CNT refining step as to needlessly remove impurities except nanotubes, and can suppress deterioration of electron emission characteristic due to bundle diameter increase.;SOLUTION: The CNT film 12 comprises carbon nanotubes (CNT) and particulate impurities, wherein the area ratio between CNT 12a and particulate impurities in cross section and surface structures is set in a range of 0.5:99.5 to 40:60. In the CNT film 12, the particulate impurities can be composed of impurities obtained together with the CNT 12a when the CNT 12a is produced.;COPYRIGHT: (C)2011,JPO&INPIT
