FIELD EMISSION DISPLAY DEVICE

摘要

PURPOSE: A field emission display device is provided to apply a cathode driving voltage to a focus electrode without using a separate power source. CONSTITUTION: A field emission display device comprises an anode and cathode substrates(10,12) spaced apart from each other; a line pattern cathode electrode(14) provided on the cathode substrate and a first insulating layer(18) covering the cathode electrode; a line pattern gate electrode(16) provided on the first insulating layer and a second insulating layer(20) covering the gate electrode; a gate hole(24) for exposing a part surface of the cathode electrode at a pixel region where the cathode and gate electrodes are intersected; an emitter(26) provided on the surface of the cathode electrode for emitting electrons when forming electric field; a via hole(28) for exposing a part surface of the cathode electrode at non-pixel region; a line pattern focus electrode(22) provided on the second insulating layer; a connecting unit(30) for connecting electrically the focus electrode to the cathode electrode; and a line pattern anode electrode(32) provided on the anode substrate and a phosphor layer(34) provided on the anode electrode.
