摘要:
A flat panel image display device comprises: 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, wherein the metal back film has a getter material, and a current luminance characteristic of the fluorescent member satisfies γ≧0.9 if L=klγ (L is luminance, l is an irradiation current, and k is a constant). Thus, a high contrast can be acquired even if electrons scattered backward again bombard and penetrate into the fluorescent member.
