BRIEF DESCRIPTION OF THE DRAWINGS
These and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the aspects, taken in conjunction with the accompanying drawings of which:
FIG. 1 is a partial exploded perspective view of an electron emission display according to an aspect of the present invention.
FIG. 2 is a partial sectional view of an electron emission display shown in FIG. 1.
FIG. 3 is a partial amplified plan view of the electron emission device according to an aspect of the present invention.
FIG. 4 is a partial amplified plan view of an electron emission device illustrating a variant of a focusing electrode.
FIG. 5 schematically illustrates the trajectories of the electron beams emitted from the center of an electron emission region of an electron emission display according to an aspect of the present invention.
FIG. 6 schematically illustrates the trajectories of the electron beams emitted from the edge of an electron emission region of an electron emission display according to an aspect of the present invention.
FIG. 7 is a graph illustrating the widths of main and sub electron beams measured when the ratio of a width of an electron emission region to a width of an opening of a gate electrode of an electron emission display is varied according to an aspect of the present invention.
