A field emission backlight unit comprises a substrate, first electrodes and second electrodes, a fluorescent lighting panel and an anode plate. The first electrodes are disposed on the substrate. The second electrodes are interlaced with the first electrodes and disposed on the substrate. The second electrodes receive a clock signal sequentially according to a first period. The fluorescent lighting panel is disposed at the opposite side of the substrate. The anode plate is disposed at the opposite side of the substrate. When there is a specific voltage between the first electrodes and the second electrodes to generate electrons, the anode plate pulls electrons to hit the fluorescent lighting panel to emit light.
