To provide a carbon film that can keep power consumption low while carrying out mechanically and electrically stable electron emission required for light emission on a requested luminance level.

Walls 4 connected in curve shape on a substrate are formed in mesh shape as walls for restricting the arrangement spacing of electron emission points, and carbon nanotubes 8 with the tips used as the electron emission points are formed higher than the walls 4 of mesh shape within a region surrounded by the walls 4 of mesh shape. Wall-like films 10 are formed on the carbon nanotubes 8 so as to spread in a form of twining from the film lower parts of the carbon nanotubes 8 to the film intermediate parts.
