PROBLEM TO BE SOLVED: To provide a liquid in which fine particles having psudo-one- dimensional shape like carbon nanotube or graphite nanotube, or the like, easy to coagulate are dispersed, its producing method, a method for efficiently refining particles, a uniform film of the fine particles with high density, an electron discharge element capable of discharging a long life electron stably and efficiently, and a facial luminescence apparatus, an apparatus for displaying an image, a solid vacuum device, a plasma display panel and a liquid crystal displaying apparatus. SOLUTION: A first conductive electrode is formed on a supporting part. The dispersed liquid of carbon nanotube or graphite nanotube dispersed in a dipolar non-proton solvent is coated by dropping or printing on the first conductive electrode and then the film containing the fine particles is layered. |
