Abstract
A flat display includes a closed vessel having a front panel (optically transparent) and a back panel, apparatus for emitting electrons by field emission positioned on the back panel, an anode having an anode electrode and at least a phosphor layer positioned on the front panel, and a spacer for defining a distance between the front panel and the back panel. The spacer has an upper cross-section adjacent to the front panel and a lower cross-section adjacent to the back panel. The lower cross-section is larger than the upper cross-section.
