A field emitter array, and a method for manufacturing the same are provided. The field emitter array comprises a nickel substrate, and a plurality of nano-pillars extending perpendicular to the nickel substrate. Each of the nano-pillars comprises a nickel nano-pillar body integrated to the nickel substrate and extending perpendicular to the nickel substrate, and an upper portion of the nano-pillar comprising a CNT-nickel composite material. At least one CNT is exposed from an upper surface of the upper portion of the nano-pillar. Since the CNTs are provided on the upper surface of the nano-pillars, field emission efficiency can be further enhanced. Additionally, since the substrate, and the nano-pillars extending perpendicular to the substrate are integrated and formed of the same material, contact resistance between the substrate and the nano-pillars is reduced, thereby enhancing the field emission efficiency.
