Abstract
An electron emission display including an electron emission substrate having at least one electron emission device formed thereon and an image forming substrate spaced apart from the electron emission substrate. The image forming substrate includes an effective region where electrons emitted from the electron emission device collide with the effective region to form images and a black region surrounding the effective region. The effective region includes a fluorescent layer formed in an arbitrary pattern and a metal layer formed on the fluorescent layer. The metal layer has a structure extending onto at least a portion of the black region.
