Abstract
An electron emission display comprising an electron collector or metal member is provided. The electron emission display comprises an electron emission substrate comprising at least one electron emission device and an image forming substrate comprising at least one emission region and at least one non-emission region. Images are formed in the emission regions by the collision of electrons emitted from the electron emission devices with the emission regions. The image forming substrate further comprises a metal layer positioned on at least the emission regions, and at least one electron collector positioned in the non-emission region. The electron collector may comprise first and second ends, wherein the first end is attached to the image forming substrate and the second end faces the electron emission substrate. The electron collector stabilizes the metal layer and fluorescent layers, thereby reducing arc and maintaining uniform brightness by re-directing scattered electrons toward the fluorescent layers.
