An electron emission film includes a matrix consisting essentially of amorphous carbon and fullerene-like structures consisting essentially of a two-dimensional network of six-membered carbon rings. The fullerene-like structures are dispersed in the matrix and partially project from the matrix. The weight ratio of amorphous carbon to the fullerene-like structures is about 50:50 to 5:95. Amorphous carbon contains nitrogen acting as a donor at a concentration of about 4&times;10 to 10 atom %.
