A process was developed for fabrication of diodetype carbon nanotube/nanofiber（CNT/CNF） field emission display (c-FED). The CNT/CNF was prepared by low pressure chemical vapor deposition. The anode and cathode were fabricated by screen printing of phosphor and CNT/CNF paste on glass plates. The vacuum package of the c-FED was fabricated like that of vacuum fluorescent display. The fully sealed c-FED exhibited a good emission property with a turnon field of 1.8 V/μm, and the emission current density of 1 mA/cm2 at 2.9 V/μm，the luminance of 600 cd/m2 for yellow light at on applied field of 2.7 V/μm, and uniform emission luminescence. The process has the advantages of low operating temperature compatible with glass substrates, a scalability in CNT/CNF yield and display size, and has a potential for practical application.
