A Field Emission Device (FED) with a quadruple lens structure includes: a rear substrate on which a cathode electrode is formed; emitters formed on the cathode electrode and adapted to emit electron beams; a gate electrode placed above an upper surface of the cathode electrode and adapted to extract electrons from the emitters; a front substrate facing an upper surface of the rear substrate where an anode electrode and a fluorescent layer are formed on a lower surface of the front substrate; and a quadruple lens structure corresponding to each of the emitters and formed between the cathode electrode and the anode electrode.
