Abstract: The phosphor screen is capable of minimizing the spread of lights in the phosphor screen, so as to restrict fading images and lowering contrast. The phosphor screen comprises a lot of minute phosphor sections. The phosphor sections are respectively enclosed by barriers, which absorb visible lights and have electric conductance, and whose height is equal to or higher than a half of thickness of the phosphor sections. The barriers are made of a material including the particles of an inorganic compound, whose average diameter is 1-8 &mgr;m, and carbon particles, whose average diameter is less than 1 &mgr;m.
