Field emission display having grid plate

A field emission display, comprising:

• a first substrate and a second substrate facing one another and having a predetermined gap therebetween;
• an electron emission assembly formed on the first substrate for emitting electrons;
• an illumination assembly formed on the second substrate for displaying images responsive to electrons emitted from the electron emission assembly;
• and
• a grid plate mounted between the first and second substrates and configured to focus the electrons emitted from the electron emission assembly,
• wherein the grid plate includes protrusions integrally formed thereon and extending from at least one side thereof, and
• wherein the protrusions form a barrier configured to receive misdirected electrons of the electrons emitted from the electron emission assembly to hinder the misdirected electrons from hitting an unintended portion of the illumination assembly.
