Abstract:
1. 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 substrate and the second substrate and configured to focus the electrons emitted from the electron emission assembly; wherein the grid plate includes a mask section having a plurality of apertures for passing the electrons and having supports mounted to one side of the mask section and extending in a direction toward the first substrate to support the mask section from the first substrate, wherein the mask section has a predetermined mask section thickness and the supports have a predetermined support height, the predetermined support height being greater than the predetermined mask section thickness, wherein the supports are made of a conducting material, and wherein the mask section and the supports are made of same material.
