ABSTRACT:
An electron emission display including a first substrate having at least one electron emission device and a second substrate opposite the first substrate. The second substrate is formed with an effective region and a non-effective region. The effective region includes a fluorescent layer for emitting light by collision with electrons emitted from the electron emission device. The non-effective region includes a region in which a light-shielding layer has a transparent conductive layer and a metal layer. The transparent conductive layer is formed in the effective region where the fluorescent layer is absent. The second substrate improves the brightness of light emitted from the fluorescent layer and prevents a power supply layer, to which a high voltage is applied, from being damaged, because the transparent conductive layer is not formed under the effective region.
