Abstract
A field emission display includes a first substrate and a second substrate that face one another with a predetermined gap therebetween. An electron emission assembly that emits electrons by generating an electric field is formed on the first substrate, and an illumination assembly that realizes the display of images responsive to the emitted electrons is formed on the second substrate. A grid plate is mounted between the first and second substrates and is configured to focus the emitted electrons. The grid plate includes a mask section having apertures through which electron beams formed by the emitted electrons are passed, and protrusions integrally formed thereon and extending from one side of the mask section to support the mask section over the first substrate.
