A field emission device exhibiting uniform field emission properties and a method for manufacturing the same are provided. The field emission device comprises a metal layer formed on a substrate, a current limiting layer formed on the metal layer, and a plurality of carbon nanotube emitters formed on the current limiting layer. The current limiting layer limits current flowing from the metal layer to the carbon nanotube emitters to a specific value. The current limiting layer can be formed of a ceramic or polymer material exhibiting a positive temperature coefficient (PTC) property.
