Field emission panel, liquid crystal display and field emission display having the same

A display apparatus including a field emission panel having a lower plate which emits electrons and an upper plate which generates white light or a color image through collision with the electrons;

• wherein the lower plate comprises:
• a plurality of electron emission elements;
• a plurality of cathode electrodes and at least one gate electrode which act jointly to form electric fields for stimulating electron emission from each respective one of the plurality of electron emission elements;
• and
• a glass plate supporting the electron emission elements, the cathode electrodes, and the gate electrodes;
• wherein the at least one gate electrode is arranged on an upper surface of the glass plate, and the glass plate includes a plurality of accommodation grooves, each of which accommodates a respective one of the plurality of electron emission elements and a respective one of the plurality of cathode electrodes.

A field emission panel, comprising:

• an upper plate;
• and
• a lower plate arranged in parallel with the upper plate, the lower plate including a plurality of electron emission elements, a plurality of cathode electrodes, a gate electrode, and a glass plate having a plurality of accommodation grooves,
• wherein the gate electrode is arranged on an upper surface of the glass plate, and wherein each of the plurality of accommodation grooves accommodates a respective one of the plurality of electron emission elements and a respective one of the plurality of cathode electrodes.

A method of fabricating a field emission panel, comprising:

• forming a plurality of accommodation grooves in a glass plate;
• positioning a cathode electrode and an electron emission element within each of the plurality of accommodation grooves;
• arranging a gate electrode having a plurality of through-holes along an upper surface of the glass plate;
• and
• arranging an upper plate in parallel with the upper surface of the glass plate, the upper plate including an anode electrode,
• wherein each respective electron emission element is configured to emit electrons stimulated by an electric field formed between the respective cathode electrode and the gate electrode, and wherein the emitted electrons are accelerated toward the upper plate by an electric field formed between the anode electrode and the gate electrode.
