Abstract: An electron emission device includes a substrate, a cathode electrode that is formed on the substrate, and one or more electron emission regions that are electrically connected to the cathode electrode. Pixel regions correspond to cross over areas of the cathode electrode and gate electrodes. The cathode electrode includes a main electrode including one or more openings corresponding to the pixel regions and two or more separated portions on two sides of the openings and a resistive layer electrically connected to the electron emission region. The separated portions have substantially identical widths. The electron emission regions are located inside the openings. Equal widths of the separated portions cause a uniform voltage on two sides of the electron emission regions and therefore a more uniform emission of electrons.
