Abstract
A field emission display including a first and a second substrate being separate and facing each other, one or more gate electrodes formed on the first substrate, and cathode electrodes formed on the one or more gate electrodes while interposing an insulating layer. The cathode electrode having a double-layered structure, an electron emission source contacting the cathode electrodes, at least one anode electrode formed on the second substrate, and a phosphor screen formed on the anode electrode.
Claims10
A field emission display, comprising:
- a first substrate and a second substrate facing each other;
- a gate electrode formed on the first substrate;
- a cathode electrode formed on the gate electrode while interposing an insulating layer, the cathode electrode having a double-layered structure of a first electrode layer directly on the insulating layer and a second electrode layer on the first electrode layer, the second electrode layer completely covering the upper surface of the first electrode layer in a pixel region;
- an electron emission source contacting the cathode electrode;
- an anode electrode formed on the second substrate;
- and
- a phosphor screen formed on the anode electrode.
