ABSTRACT:
A flat panel image display device includes a rear plate including plural electron emission elements, a face plate disposed opposed to the rear plate, fluorescent members being disposed on a surface of the face plate opposed to the rear plate, and the fluorescent members being covered with a metal back film, and a voltage applying unit to apply an acceleration voltage of 8 kV to 15 kV between the rear plate and the face plate. In addition, the metal back film has a getter material, and a current luminance characteristic of the fluorescent member satisfies γ≧0.9 if L=klγ , wherein L is luminance, l is an irradiation current, and k is a constant.
