Abstract:
1. An image forming apparatus comprising: a rear plate having an electron emitting device; and a face plate having a substrate, a fluorescent layer disposed on the substrate and a conductive film disposed on said fluorescent layer, wherein said fluorescent layer comprises a plurality of pixel areas, arranged in a matrix form or in a stripe form, each of which comprises a fluorescent film and a light absorption member adjacent to the fluorescent film, the fluorescent film comprising fluorescent particles, wherein the conductive film is formed on the fluorescent film in a continuous manner, and wherein when an average thickness of said fluorescent layer in one pixel area is set to d, an average particle diameter of said fluorescent particles is rp, and the thickness of the fluorescent layer at any point in the one pixel area is D, d−rp≦D≦d+rp is satisfied.
