Abstract:
A flat panel display device and a manufacturing method thereof are provided to suppress arc discharges caused by a distortion of an electric field by generating a flat electric field on a metal reflection film. A flat panel display device includes an electron emitter(101) and a light emitter(110). The light emitter emits visual rays to a front portion of the display device. The light emitter includes a front substrate(111), a fluorescent film(113), and a metal reflective film(120). The front substrate passes the visual ray. The fluorescent film is formed on a rear surface of the front substrate. The fluorescent film is illuminated by electrons, which are emitted from the electron emitter. The metal reflective film is arranged between the fluorescent film and the electron emitter. The metal reflective film is separated from the fluorescent film.
