Abstract

A flat panel display includes a substrate, a front glass, a cathode, a gate electrode, a plurality of front ribs, a phosphor film and a metal-backed film, and a gate rib. The front glass is arranged to oppose the substrate and forms a vacuum envelope together with the substrate. The front glass is transparent at least partially. The cathode is arranged on the substrate. The gate electrode is arranged between the substrate and front glass and includes an electron-passing hole through which an electron emitted from the cathode passes. The front ribs extend vertically at a predetermined interval from the front glass toward the gate electrode. The phosphor film and metal-backed film are stacked on a region of the front glass which is sandwiched by the front ribs. The gate rib extends vertically from the gate electrode toward the front glass and is in contact with the front ribs. A gate electrode structure and a gate electrode structure manufacturing method are also disclosed.
