A field emission device includes a transparent anode substrate, an anode, a cathode substrate, a cathode, and a fluorescent layer. The anode is formed on the anode substrate. The cathode is formed on the cathode substrate. The cathode faces toward the anode and is spaced therefrom at a predetermined distance. The fluorescent layer is formed on the cathode and faces toward the anode. A method for manufacturing the field emission device is also disclosed.
