  • Publication number: 20060175950
    Abstract: It is a field electron emission film which is able to form a field electron emission film less in the amount of residual gas and stable in the amount of emitted electrons. Because it is formed in thin film, resistivity value of the film within the plane becomes even, and this is a field electron emission film having excellent smoothness, and higher electron emission property. Carbon nanotube structural body of 0.001 to 40% by weight, and a heat decomposition product of 0.01% by weight or more obtained by heat decomposition of a heat-decomposable metal compound are included. Organo-metallic compound, metal salt, organo-metallic salt compound and metal complex are preferable as the heat-decomposable metal compound.
