The present invention proposes a field emitting display, wherein a field emitting array is formed on a glass substrate. The field emitting array comprises a plurality of arrays of thin film transistors and a plurality of carbon nanotubes used as field emitting cathodes. The magnitude and stability of the field-emitted current of the carbon nanotubes are controlled by using the thin film transistors. The present invention has the characteristics of high quality, large area, and low cost.
