Abstract
An electron emission device is disclosed. The electron emission device includes a cathode electrode including a main electrode having an opening, ii) a plurality of isolated electrodes on each of which each of plurality of electron emission units is located, and iii) at least one resistance layer electrically connecting the main electrode and the plurality of isolated electrodes. The plurality of isolated electrodes are located within the opening and form gaps with the main electrode. A resistance between the main electrode and one of the plurality of isolated electrodes is different from that between the main electrode and the other isolated electrodes.
