ABSTRACT:
A field emission device includes a transparent plate, an insulating substrate, one or more grids located on the insulating substrate. Each grid includes a first, second, third and fourth electrode down-leads and a pixel unit. The first, second, third and fourth electrode down-leads are located on the periphery of the grid. The first and the second electrode down-leads are parallel to each other. The third and the fourth electrode down-leads are parallel to each other. The pixel unit includes a phosphor layer, a first electrode, a second electrode and at least one electron emitter. The first electrode and the second electrode are separately located. The first electrode is electrically connected to the first electrode down-lead, and the second electrode is electrically connected to the third electrode down-lead. The phosphor layer is located on the corresponding first electrode.
