We show the relationship between the property of field electron emission, the area of patterned CNTs bundle, and the density of CNTs bundle. The current density can reach as high as 20 mA/cm2 at about 1.40 V/um. We define the threshold electric field as that which corresponds to the current density of 1.0 mA/cm2. It shows that the lowest threshold electric field of 0.87 V/um was obtained with the total area percentage of 46% which synthesized with 25 mm of diameter and 10 mm of pitch.
