1. An electron emission display comprising:
an electron emission substrate comprising at least one electron emission device; and
an image forming substrate comprising:
at least one fluorescent layer;
a metal layer positioned over the at least one fluorescent layer; and
at least one electron collector positioned on the metal layer in at least one region of the image forming substrate where no fluorescent layers are positioned, the at least one electron collector being between the metal layer and the electron emission substrate and spaced apart from the electron emission substrate,
wherein the at least one electron collector comprises a first collector end and a second collector end, the first collector end facing the metal layer of the image forming substrate, the second collector end facing the electron emission substrate, the second collector end having an outer parameter larger than that at the center of the at least one electron collector.
