PURPOSE: A field emission device having a multilayer insulator has a hetero-multilayer insulator contacted with a fluorescent layer. CONSTITUTION: A field emission device has at least one fluorescent substance, and an insulator contacted with at least one fluorescent substance. The insulator is a hetero-multilayer insulator wherein first and second insulation layers are alternately deposited. A relative permittivity of the first insulation layer is lower than that of the second insulation layer, and a breakdown field of the first insulation layer is higher than that of the second insulation layer, thereby lowering a driving voltage by using a multiplayer dielectric substance as of Al2O3 and Ta2O5. Also, the field emission device achieves a maximum luminance at a low modulation voltage.
