Abstract
A phosphor capable of being reduced in activity of a surface thereof, to thereby minimize adsorption of gas thereon, release of gas therefrom and the like, to thereby ensure protection of the surface. The phosphor of the present invention is coated with a diamond-like carbon (DLC) film. Such coating reduces an activity of a surface of the phosphor. Also, the phosphor may be used for a display section of a display device. This permits durability of the phosphor to be increased and prevents a deterioration of a cathode, resulting in the display device being increased in durability.
