Abstract
A field emission display device (FED) is disclosed. The FED disclosed herein includes: a upper substrate, an anode layer, a phosphor layer, a lower substrate, at least one cathode, at least one electron emitter, and an partition plate set located between the upper substrate and the lower substrate. The partition plate set includes at least one nonmetal dielectric plate having plural holes, at least one insulation layer, and at least one gate. The FED of the present invention can simplify the process and reduce the damage caused by the manufacturing process, effectively increase the number of the electrons bombarding the phosphor layer, and increase the brightness and contrast ratio of the pixels.
