    • PURPOSE: A MIC(Metal-Insulator-Carbon) type field emission device using carbon nanotubes and insulators is provided, which can control an emission current easily by locating a gate electrode below a cathode. CONSTITUTION: A mesh-grid(180) is inserted between a cathode(121) and an anode(140) to control the spreading of emission electrons due to an edge emission, and thus a color separation can be improved. The mesh-grid can prevent an electric field of the anode from influencing on the cathode when a high voltage is applied to the anode to obtain a high brightness. According to the fabrication sequence of an under-gate structure, a gate is formed on a substrate and an insulation layer is placed on the gate, and then the cathode is formed on the insulation layer. After coating a mixed material of a carbon nanotube and a dielectric material along the cathodes or on a dot region where the cathodes are overlapped with the gates, a front substrate(200) and a rear substrate(110) are sealed in vacuum using a spacer(160).
