ABSTRACT:
A field emission display device is arranged to improve the (luminance and the contrast and have a fluorescent screen for preventing a fluophor from being stripped off a substrate. The field emission display device includes a cathode electrode, the fluophors excited by electrons emitted by the cathode electrode, an anode electrode to which a given anode voltage is to be applied, and a metal film formed on the fluophors. The metal film is formed to have a thickness in the range of 2.times.10.sup.-6 E<t<2.times.10.sup.-5 E+0.02, where t is a thickness of the metal film and E is a voltage to be applied onto the anode electrode.
