A field emission display (FED) is provided. The FED has an emitter
structure where the emitter, a conductor and a cathode electrode are so
arranged to produce a certain electric field about the emitter. The
electric field about the emitter causes the electron beam emitted from
the emitter to have improved focus and have less dispersion. This causes
the electron beam to hit the intended pixel without exciting phosphor
layers in neighboring pixels, thus improving image quality.
