Field emission display device for uniform dispersion of electrons

A field emission display, comprising:

• a top substrate;
• a bottom substrate comprising:
• at least one cathode electrode on a bottom panel and having an opening-pattern having at least one opening;
• an insulating layer on the cathode electrode, wherein the insulating layer has an opening-pattern with at least one opening, and the opening-pattern of the insulating layer is the same as that of the cathode electrode and the width of the opening of the cathode electrode and the width of the opening of the insulating layer are the same;
• at least one gate electrode on the insulating layer;
• and
• at least one electron emitter in an opening of the opening-pattern of the cathode electrode and the electron emitter has the same height as that of the cathode electrode, wherein the opening of the cathode electrode is filled with the electron emitter having a flat surface, and the electron emitter directly contacts the bottom panel;
• wherein the electron emitter is adjacent to the cathode electrode and is electrically connected therewith.
